                            PSYCHEMEDICS CORPORATION

                            1280 Massachusetts Avenue
                         Cambridge, Massachusetts 02138

                                 PROXY STATEMENT

                         ANNUAL MEETING OF STOCKHOLDERS
                           TO BE HELD ON MAY 10, 2001


     This statement is furnished to the stockholders of PSYCHEMEDICS CORPORATION
(hereinafter, the "Company") in connection with management's solicitation of
proxies to be used at the Annual Meeting of Stockholders on May 10, 2001 and at
any adjournment of that meeting. The approximate date on which this proxy
statement and accompanying proxy are being sent to stockholders of the Company
is April 2, 2001. Each proxy delivered pursuant to this solicitation is
revocable at the option of the person executing the same by written notice
delivered to the Secretary of the Company at any time before the proxy is voted.
A stockholder who attends the Annual Meeting in person may revoke his or her
proxy at that time and vote his or her shares if such stockholder so desires.
The presence in person or by proxy of stockholders entitled to cast a majority
of the outstanding shares, or 10,576,689 shares, shall constitute a quorum. With
respect to the election of Directors, the Company will treat votes withheld as
shares that are present for purposes of determining a quorum. A plurality is
required to elect Directors, so the six persons receiving the greatest number of
votes will be elected. Withheld votes will not affect the outcome of the
election. With respect to the approval of auditors, the Company will treat
abstentions as shares that are present and entitled to vote for purposes of
determining a quorum. Since a majority of the shares represented at the meeting
and entitled to vote is required for approval, abstentions will have the effect
of a vote against approval of this proposal. If a broker indicates on a proxy
that it does not have discretionary authority as to certain shares to vote on a
particular matter, those shares will be considered as present for quorum
purposes but not as shares entitled to vote with respect to that matter.
Accordingly, broker non-votes will have no effect on such a matter.

     All shares represented by a properly executed proxy will be voted unless it
is revoked and, if a choice is specified, will be voted in accordance with such
specification. If no choice is specified, the proxies will be voted FOR the
election of the six nominees named under "Election of Directors", unless
authority to do so is withheld with respect to one or more of the nominees, and
FOR the ratification of the Company's selection of Arthur Andersen LLP as
auditors for the year ending December 31, 2001. In addition, the proxy will be
voted in the discretion of the proxy holders with respect to such other business
as may properly come before the meeting. The officers and directors of the
Company as a group own beneficially (excluding options to acquire stock)
approximately 20% of the outstanding shares of Common Stock of the Company (see
"Principal Stockholders and Stockholdings of Management"). The Company expects
that its officers and directors will vote the shares owned by them FOR the
election of such six nominees and FOR the ratification of the Company's
selection of Arthur Andersen LLP as auditors.

     As of March 15, 2001, the Company had outstanding 21,153,376 shares of
Common Stock. Each share of the outstanding Common Stock is entitled to one
vote. Only holders of Common Stock of record on the books of the Company at the
close of business on March 15, 2001 will be entitled to receive notice of, and
to vote at, the Annual Meeting.

                              ELECTION OF DIRECTORS

     At the Annual Meeting, directors are to be elected to hold office for the
ensuing year and until their respective successors are chosen and qualified. The
Board of Directors has fixed the size of the Board at six and has nominated six
persons, all of whom are now directors of the Company, to serve until the next
Annual Meeting of Stockholders and until their successors are elected and
qualified. If the enclosed proxy is duly executed and received in time for the
Meeting, and unless authority to do so is withheld, it will be voted to elect as
directors the following nominees: Raymond C. Kubacki, Jr., Werner A.
Baumgartner, Ph.D., A. Clinton Allen, Donald F. Flynn, Walter S. Tomenson, Jr.
and Fred J. Weinert. (For a description of the business experience of such
nominees, see "Business Experience of Nominees and Executive Officers" below.)
In the event that any of the nominees become unavailable, then the proxy holders
shall have the right: (i) to vote for such substitute, if any, as the present
Board of Directors may designate; or (ii) to leave a vacancy on the Board.

     The Company does not have any nominating or compensation committees of the
Board of Directors. The Audit Committee, whose members are Messrs. Flynn,
Tomenson and Weinert, held one meeting during 2000. Each of the members of the
Audit Committee is independent within the meaning of the listing standards for
the American Stock Exchange. The Stock Option Committee, whose members are
Messrs. Flynn, Tomenson and Weinert, administers the Company's stock option
plans, including the determination of persons who are to be granted options
under such plans, the number of shares subject to each option, and the term of
each option. The Stock Option Committee held one meeting in 2000.

     During the year ended December 31, 2000, there were two meetings of the
Board of Directors. All of the directors attended both meetings, except for Mr.
Flynn and Dr. Baumgartner, who each attended only one meeting. The directors
also acted by unanimous written consent on ten occasions during 2000. The
directors regularly consult with management and are kept informed of business
developments and financial results as they occur.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Based solely on its review of copies of reports filed pursuant to Section
16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
or written representations from persons required to file such reports
("Reporting Persons"), the Company believes that except as described below, all
such filings required to be made by such Reporting Persons were timely made in
accordance with the requirements of the Exchange Act. Dr. Baumgartner filed Form
4's to report the sales of shares in 13 transactions which took place in May and
June, 2000 after the dates specified therefor.

                          REPORT OF THE AUDIT COMMITTEE

     The following Report of the Audit Committee does not constitute soliciting
material and should not be deemed filed or incorporated by reference into any
other Company filing under the Securities Act of 1933 or the Securities Exchange
Act of 1934, except to the extent the Company specifically incorporates this
Report by reference therein.

     On May 11, 2000, the Board of Directors adopted a charter for the Audit
Committee. The complete text of the new charter, which reflects standards set
forth in new SEC regulations and American Stock Exchange rules, is attached
hereto as Exhibit A to this proxy statement. As set forth in more detail in the
charter, the Audit Committee's primary responsibilities fall into three broad
categories:

     first, the Committee is charged with monitoring the preparation of
     quarterly and annual financial reports by the Company's management,
     including discussions with management and the Company's auditors about
     draft annual financial statements and key accounting and reporting matters;

     second, the Committee is responsible for matters concerning the
     relationship between the Company and its auditors, including recommending
     their appointment or removal; reviewing the scope of their audit services
     and related fees, as well as any other services being provided to the
     Company; and determining whether the auditors are independent (based in
     part on the annual letter provided to the Company pursuant to Independence
     Standards Board Standard No. 1); and

     third, the Committee oversees management's implementation of effective
     systems of internal controls, including review of policies relating to
     legal and regulatory compliance, ethics and conflicts of interests.

     The Committee has implemented procedures to ensure that during the course
of each fiscal year it devotes the attention that it deems necessary or
appropriate to each of the matters assigned to it under the Committee's charter.
In overseeing the preparation of the Company's annual financial statements for
the year ending December 31, 2000, the Committee met with both management and
the Company's auditors to review and discuss such financial statements prior to
their issuance and to discuss significant accounting issues. Management advised
the Committee that such financial statements were prepared in accordance with
generally accepted accounting principles, and the Committee discussed the
statements with both management and the auditors. The Committee's review
included discussion with the auditors of matters required to be discussed
pursuant to Statement on Auditing Standards No. 61 (Communication With Audit
Committees). With respect to the Company's auditors, the Committee, among other
things, discussed with Arthur Andersen LLP matters relating to its independence,
including the disclosures made to the Committee as required by the Independence
Standards Board Standard No. 1 (Independence Discussions with Audit Committees).
On the basis of these reviews and discussions, the Committee recommended to the
Board of Directors that the Board approve the inclusion of the Company's audited
financial statements in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 2000, for filing with the Securities and Exchange
Commission.

     Exchange) minus the exercise price per share, of the in-the-money options,
     multiplied by the number of shares subject to each option.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

     In connection with the grants by the Company to Mr. Kubacki and to Mr.
Thistle of options to acquire shares of the Company's Common Stock, the Company
agreed that notwithstanding the vesting schedule stated in the applicable option
agreement, such options would become exercisable in full upon a
change-in-control of the Company. The following events constitute a
change-in-control for purposes of the option agreements: (a) the aggregate
number of shares beneficially owned by the group of investors which purchased
securities of the Company on May 15, 1989 is less than the number held by any
other person or group, (b) the Company sells, leases or transfers all or
substantially all of its assets, or (c) the Company merges or consolidates with
another company and the existing stockholders of the Company end up owning less
than 50% of the combined company.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During fiscal year 2000, Dr. Baumgartner, and Messrs. Kubacki and Allen,
each of whom was both a director and an executive officer of the Company during
the year ended December 31, 2000, participated in deliberations of the Board of
Directors during such year concerning executive officer compensation.

BOARD OF DIRECTORS REPORT ON EXECUTIVE COMPENSATION

The following Report of the Compensation Committee and the Stock Option
Committee and the performance graph included elsewhere in this proxy statement
do not constitute soliciting material and should not be deemed filed or
incorporated by reference into any other Company filing under the Securities Act
of 1933 or the Securities Exchange Act of 1934, except to the extent the Company
specifically incorporates this Report or the performance graph by reference
therein.

          The Company's executive compensation program is designed to attract,
     retain and reward executives who are responsible for leading the company in
     achieving its business objectives. This report is submitted by the Board of
     Directors and addresses the compensation policies for fiscal 2000 as they
     affected Mr. Kubacki, in his capacity as Chief Executive Officer of the
     Company, and the other executive officers of the Company.

          COMPENSATION PHILOSOPHY

          The Company's executive compensation philosophy is based on the belief
     that competitive compensation is essential to attract, motivate and retain
     highly qualified and industrious employees. The Company's policy is to
     provide total compensation that is competitive for comparable work and
     comparable corporate performance. The compensation program is also designed
     to link the interests of the Company's executives to the interests of the
     Company's shareholders.

          At present, the executive compensation program is comprised of salary,
     cash incentive opportunities, long-term incentive opportunities in the form
     of stock options, and benefits typically offered to executives by major
     corporations. As an executive's level of responsibility increases, the
     greater the mix of compensation shifts to reliance on the value of the
     Common Stock through stock-based awards.

          Section 162(m) of the Internal Revenue Code generally disallows a tax
     deduction to a public company for compensation over $1 million paid to its
     chief executive officer and its four other most highly compensated
     executive officers. Qualifying performance-based compensation is not
     subject to the deduction limit if certain requirements are met. It is the
     Board's objective to maximize deductibility under Section 162(m) with
     minimal sacrifices in flexibility and corporate objectives. Accordingly,
     with respect to compensation payable to an applicable executive officer
     which would otherwise be nondeductible, it is the Company's policy that
     such amounts be deferred until the limitation on deductibility no longer
     applies with respect to such person.

          COMPENSATION ELEMENTS

               BASE SALARY

          At the executive officer level, base salaries are conservative when
     compared with companies of similar size and financial performance. Salary
     ranges are assigned to each position based on a comparison of the Company's
     positions with similar positions in companies of similar size in the
     Company's industry, with range midpoints established at the average of the
     marketplace. Actual salaries within the appropriate range depend upon
     individual performance, experience and internal equity and are reviewed and
     may be adjusted annually by the Company. Salary levels for executives other
     than the Chief Executive Officer were determined for 2000 by Mr. Kubacki,
     the Chief Executive Officer, based on the foregoing criteria.

               INCENTIVE COMPENSATION

          The Company has generally not paid cash bonuses to executive officers
     as rewards for superior performance, preferring instead to reward executive
     officers with equity-based compensation in the form of stock options.

               STOCK OPTIONS

          In May, 2000, the Company adopted a new stock option plan for
     officers, directors, and employees called the Psychemedics Corporation 2000
     Stock Option Plan (the "2000 Stock Option Plan"). The 2000 Stock Option
     Plan superceded the Company's 1989 Employee Plan. Under the 2000 Stock
     Option Plan the Stock Option Committee of the Board of Directors may grant
     options with terms of up to ten years. The options generally become
     exercisable with respect to 25% of the shares covered thereby on the first
     anniversary of the date of grant and with respect to an additional 25% on
     each of the next three anniversary dates thereafter. In granting the stock
     options to executives, the Stock Option Committee of the Board of Directors
     takes into account the practices of other companies of comparable size as
     well as the executive's level of responsibility and past contributions to
     the Company, particularly in light of the Company's practice not to award
     cash bonuses. In May, 2000, the Stock Option Committee granted options to
     executive officers of the Company, other than the Chief Executive Officer,
     and to other key employees of the Company based on 1999 operating results.

          COMPENSATION TO THE CHIEF EXECUTIVE OFFICER

          Mr. Kubacki's annual base salary was last adjusted in May, 1999. In
     establishing the rate of salary, the Board considered the Company's
     financial performance for the prior year and over an extended period of
     time, Mr. Kubacki's individual performance, and his long-term contributions
     to the success of the Company. Mr. Kubacki did not receive an increase in
     salary in 2000. At his request, the Board did not grant to Mr. Kubacki any
     stock options in 2000.

COMPENSATION OF DIRECTORS

     Messrs. Kubacki, Baumgartner and Allen receive no additional compensation
for serving on the Company's Board of Directors. The Company's outside
(non-employee) directors each receive cash compensation in the amount of $5,000
for each meeting attended.

     Under the Company's 1989 Non-Qualified Stock Option Plan (the "1989
Non-Employee Director Plan"), until it was discontinued on March 21, 2000, each
outside director automatically received a grant of an option for 25,750 shares
upon his appointment to the Board. Each such option had an exercise price equal
to the market value per share of the Company's Common Stock on the automatic
grant date, had a term of ten years and became exercisable over a period of
twenty-four months from the date of grant in equal monthly installments on a
cumulative basis. Under the 1989 Non-Employee Director Plan, each outside
director also automatically received, effective March 15, of each year, a grant
of an option for 20,600 shares. Each such option was for a term of ten years,
became exercisable in full twelve (12) months after the date of grant, and had
an exercise price equal to the market value per share of the Company's Common
Stock on the automatic grant date.

     Options under the 1989 Non-Employee Director Plan were not transferable by
the optionee otherwise than by will or the laws of descent and distribution and
terminated if the optionee ceased to serve as a member of the Company's Board of
Directors. In the event of the optionee's death or permanent disability, the
option became exercisable in full and the optionee or his heirs, legatees or
legal representatives could exercise the option during the following one year
period or the remainder of the option term, whichever period is shorter.

     On March 15, 2000, each outside director was granted an option to acquire
20,600 shares at an exercise price of $5.13 per share, representing the market
price on the date of grant. Each such option was granted under the 1989
Non-Employee Director Plan.

     Directors are also eligible to receive the grant of discretionary options
under the Company's 2000 Stock Option Plan.

                         INDEPENDENT PUBLIC ACCOUNTANTS

     The Board of Directors has selected as the Company's independent auditors
for the year ended December 31, 2001, the firm of Arthur Andersen LLP and
recommends ratification of such selection by the stockholders. A representative
of Arthur Andersen LLP is expected to be present at the Annual Meeting and will
be available to respond to appropriate questions.

     For the year ended December 31, 2000, Arthur Andersen LLP billed the
Company for services in the following categories:


                                         
Audit Fees                                  $40,000
Financial Information Systems Fees                0
All Other Fees (tax preparation)             20,000
                                            -------
  Total Fees                                $60,000


     The Audit Committee has considered whether the provision of non-audit
services by Arthur Andersen LLP is compatible with maintaining auditor
independence.

                              STOCKHOLDER PROPOSALS

     Proposals of stockholders intended to be presented at the next Annual
Meeting of Stockholders must comply with Rule 14a-8 of the Securities and
Exchange Commission issued under the Securities Exchange Act of 1934, and must
be received at the principal executive offices of the Company not later than
December 3, 2001.

                                  OTHER MATTERS

     The Board of Directors knows of no other matters which may come before the
Meeting. However, if any matter not now known is presented at the Meeting, it is
the intention of the persons named in the accompanying form of proxy to vote
said proxy in accordance with their judgment on such matter.

     The Company will bear the cost of solicitation of proxies. Solicitations of
proxies by mail may be followed by telephone or other personal solicitation of
certain stockholders by officers or other employees of the Company.


                                         By order of the Board of Directors,

                                    EXHIBIT A

                             AUDIT COMMITTEE CHARTER

A.   PURPOSE AND SCOPE

     The primary function of the Audit Committee (the "Committee") is to assist
the Board of Directors in fulfilling its responsibilities by reviewing: (i) the
financial reports provided by the Corporation to the Securities and Exchange
Commission ("SEC"), the Corporation's shareholders or to the general public, and
(ii) the Corporation's internal financial and accounting controls.

B.   COMPOSITION

     The Committee shall be comprised of a minimum of three directors as
appointed by the Board of Directors, who shall meet the independence and audit
committee composition requirements under any rules or regulations of The
American Stock Exchange, as in effect from time to time, and shall be free from
any relationship that, in the opinion of the Board of Directors, would interfere
with the exercise of his or her independent judgment as a member of the
Committee.

     All members of the Committee shall either (i) be able to read and
understand fundamental financial statements, including a balance sheet, cash
flow statement and income statement, or (ii) be able to do so within a
reasonable period of time after appointment to the Committee. At least one
member of the Committee shall have employment experience in finance or
accounting, requisite professional certification in accounting, or other
comparable experience or background which results in the individual's financial
sophistication, including being or having been a chief executive officer, chief
financial officer or other senior officer with financial oversight
responsibilities.

     The Board may appoint one member who does not meet the independence
requirements set forth above and who is not a current employee of the
Corporation or an immediate family member of such employee if the Board, under
exceptional and limited circumstances, determines that membership on the
Committee by the individual is required in the best interests of the Corporation
and its shareholders. The Board shall disclose in the next proxy statement after
such determination the nature of the relationship and the reasons for the
determination.

     The members of the Committee shall be elected by the Board of Directors at
the meeting of the Board of Directors following each annual meeting of
stockholders and shall serve until their successors shall be duly elected and
qualified or until their earlier resignation or removal. Unless a Chair is
elected by the full Board of Directors, the members of the Committee may
designate a Chair by majority vote of the full Committee membership.

C.   RESPONSIBILITIES AND DUTIES

     To fulfill its responsibilities and duties the Committee shall:

     DOCUMENT REVIEW

1.   Review and assess the adequacy of this Charter periodically as conditions
     dictate, but at least annually (and update this Charter if and when
     appropriate).

2.   Review with representatives of management and representatives of the
     independent accounting firm the Corporation's audited annual financial
     statements prior to their filing as part of the Annual Report on Form 10-K.
     After such review and discussion, the Committee shall recommend to the
     Board of Directors whether such audited financial statements should be
     published in the Corporation's annual report on Form 10-K. The Committee
     shall also review the Corporation's quarterly financial statements prior to
     their inclusion in the Corporation's quarterly SEC filings on Form 10-Q.


                                      A-1
   21


3.   Take steps designed to insure that the independent accounting firm reviews
     the Corporation's interim financial statements prior to their inclusion in
     the Corporation's quarterly reports on Form 10-Q.

     INDEPENDENT ACCOUNTING FIRM

4.   Recommend to the Board of Directors the selection of the independent
     accounting firm, and approve the fees and other compensation to be paid to
     the independent accounting firm. The Committee shall have the ultimate
     authority and responsibility to select, evaluate and, when warranted,
     replace such independent accounting firm (or to recommend such replacement
     for shareholder approval in any proxy statement).

5.   On an annual basis, receive from the independent accounting firm a formal
     written statement identifying all relationships between the independent
     accounting firm and the Corporation consistent with Independence Standards
     Board ("ISB") Standard 1. The Committee shall actively engage in a dialogue
     with the independent accounting firm as to any disclosed relationships or
     services that may impact its independence. The Committee shall take, or
     recommend that the Board of Directors take, appropriate action to oversee
     the independence of the independent accounting firm.

6.   On an annual basis, discuss with representatives of the independent
     accounting firm the matters required to be discussed by Statement on
     Auditing Standards ("SAS") 61, as it may be modified or supplemented.

7.   Meet with the independent accounting firm prior to the audit to review the
     planning and staffing of the audit.

8.   Evaluate the performance of the independent accounting firm and recommend
     to the Board of Directors any proposed discharge of the independent
     accounting firm when circumstances warrant. The independent accounting firm
     shall be ultimately accountable to the Board of Directors and the
     Committee.

     FINANCIAL REPORTING PROCESSES

9.   In consultation with the independent accounting firm and management, review
     annually the adequacy of the Corporation's internal financial and
     accounting controls.

     COMPLIANCE

10.  To the extent deemed necessary by the Committee, it shall have the
     authority to engage outside counsel and/or independent accounting
     consultants to review any matter under its responsibility.

     REPORTING

11.  Prepare, in accordance with the rules of the SEC as modified or
     supplemented from time to time, a written report of the audit committee to
     be included in the Corporation's annual proxy statement for each annual
     meeting of stockholders occurring after December 14, 2000.

     While the Audit Committee has the responsibilities and powers set forth in
this Charter, it is not the duty of the Audit Committee to plan or conduct
audits or to determine that the Corporation's financial statements are complete
and accurate and are in accordance with generally accepted accounting
principles.
