                            PSYCHEMEDICS CORPORATION
                          NOTES TO FINANCIAL STATEMENTS

                               September 30, 2001

1. Interim Financial Statements

The accompanying unaudited interim financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and pursuant to the rules and regulations of the Securities and
Exchange Commission for reporting on Form 10-Q. Accordingly, certain information
and footnote disclosure required for complete financial statements are not
included herein. It is recommended that these financial statements be read in
conjunction with the financial statements and related notes of Psychemedics
Corporation (the "Company") as reported in the Company's Annual Report on Form
10-K for the year ended December 31, 2000. In the opinion of management, all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation of financial position, results of operations, and cash
flows at the dates and for the periods presented have been included. The balance
sheet presented as of December 31, 2000 has been derived from the financial
statements that have been audited by the Company's independent public
accountants. The results of operations for the three months and the nine months
ended September 30, 2001 may not be indicative of the results that may be
expected for the year ending December 31, 2001, or any other period.

2. Basic and Diluted Net Income Per Share

In accordance with Statement of Financial Accounting Standard ("SFAS") No. 128,
Earnings Per Share, basic net income per share is computed by dividing net
income by the weighted average number of common shares outstanding during the
period. Diluted net income per share was computed by dividing net income by the
weighted average number of common and dilutive common equivalent shares
outstanding during the period. The number of dilutive common equivalent shares
outstanding during the period has been determined in accordance with the
treasury-stock method. Common equivalent shares consist of common stock issuable
upon the exercise of outstanding options.

     Basic and diluted weighted average common shares outstanding are as
follows:



                                 Three Months Ended              Nine Months Ended
                            -----------------------------  ------------------------------

For the three months ended September 30, 2001 and 2000, options to purchase
1,440,120 and 1,086,070 common shares, respectively, were outstanding but not
included in the diluted weighted average common share calculation as the effect
would


                                     Page 7


have been antidilutive. For the nine months ended September 30, 2001 and 2000,
options to purchase 1,078,370 and 1,086,070 common shares, respectively, were
outstanding but not included in the diluted weighted average common share
calculation as the effect would have been antidilutive.

3. Revenue Recognition

Except as provided below, revenues from the Company's services are recognized
upon reporting of drug test results to the customer. Revenues related to sample
collection kits not returned for processing by customers are recognized when the
likelihood of the Company performing any service obligation is deemed remote.
During the first quarter of 2000, the Company recorded $109,000 of revenue
related to sample collection kits that were sold for which the Company's
obligation to provide service was deemed remote. At September 30, 2001 and
December 31, 2000, the Company had deferred revenue balances of approximately
$748,000 and $636,000, respectively, reflecting payments for its personal drug
testing service received prior to the performance of the related test.

4. Comprehensive Income

The Company's comprehensive income for the three month periods and the nine
month periods ended September 30, 2001 and 2000 was the same as reported net
income.

5. Computer Software Costs

As of September 30, 2001 and December 31, 2000, $1,205,540 of software
development costs have been capitalized. For both of the three month periods
ended September 30, 2001 and 2000, $60,294 of related amortization was charged
to operations. For both of the nine month periods ended September 30, 2001 and
2000, $180,882 of related amortization was charged to operations.

6. New Accounting Pronouncements

In June 1999, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 137, Accounting for Derivative Financial Instruments and Hedging Activities
- - Deferral of the Effective Date of FASB Statement No. 133, which defers the
effective date of SFAS No. 133 to all fiscal quarters of all fiscal years
beginning after June 15, 2000. SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires entities to
recognize all derivatives as either assets or liabilities in the statement of
financial position and to measure those instruments at fair value. The Company
does not anticipate the adoption of these statements to have a material impact
on its financial position or results of operations. As of September 30, 2001,
the Company did not have any derivatives or other financial instruments as
defined by SFAS No. 119, Disclosures about Derivative Financial Instruments and
Fair Value of Financial Instruments.

On June 30, 2001, the FASB issued SFAS No. 141, Accounting for Business
Combinations, and SFAS No. 142, Accounting for Goodwill and Other Intangible
Assets. SFAS 141 requires that all business combinations initiated after
June 30, 2001 be accounted for under the purchase method. Upon adoption of SFAS
No. 142,


                                     Page 8


goodwill will no longer be subject to amortization over its estimated useful
life. Rather, goodwill will be subject to at least an annual assessment of
impairment by applying a fair-value based test. The Company does not anticipate
the adoption of these statements to have a material impact on the financial
position or results of operations.

Item 2 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


                     FACTORS THAT MAY AFFECT FUTURE RESULTS
                     --------------------------------------

From time to time, information provided by the Company or statements made by its
employees may contain "forward-looking" information which involves risks and
uncertainties. In particular, statements contained in this report which are not
historical facts (including but not limited to the Company's expectations
regarding revenues, business strategy, anticipated operating results, cash
dividends and anticipated cash requirements) may be "forward looking"
statements. The Company's actual results may differ from those stated in any
"forward looking" statements. Factors that may cause such differences include,
but are not limited to, risks associated with the expansion of the Company's
sales and marketing network, market acceptance of the Company's products,
development of markets for new products and services offered by the Company, the
economic health of principal customers of the Company, financial and operational
risks associated with possible expansion of testing facilities used by the
Company, government regulation (including, but not limited to, Food and Drug
Administration regulations), competition and general economic conditions.

                                    OVERVIEW
                                    --------

Psychemedics Corporation was incorporated in 1986. The Company utilizes a
patented hair analysis method involving radioimmunoassay technology to analyze
human hair to detect abused substances.

                              RESULTS OF OPERATIONS
                              ---------------------

Revenue was $3,955,117 for the three month period ended September 30, 2001 as
compared to $5,021,437 for the comparable period of 2000, representing a
decrease of 21%. Revenue for the nine month period ended September 30, 2001 was
$12,537,870, a decrease of 17% from the $15,176,165 of revenue reported for the
comparable period of 2000. Although the Company added new customers in the first
three quarters of 2001, this new business was outweighed by lower volume from
existing customers. The Company believes that this lower volume from existing
customers is due largely to the continued current economic downturn as many
clients experienced deep reductions in their new hires and the number of their
drug tests.

Gross margin was 50% of sales in the third quarter of 2001, as compared to 55%
in the third quarter of 2000. Gross margin for the nine months ended September
30, 2001 was 52% of sales, as compared to 55% for the nine months ended
September 30, 2000. The decreases in margins from the year earlier periods were
caused by fixed


                                     Page 9


and semi-variable direct costs being spread over a lower number of tests
performed, combined with a decrease of 1% in the Company's prices. During the
second quarter of 2001, the Company implemented cost reduction measures at its
laboratory which enabled the Company to experience a gross margin reduction of
only 2% for the nine month period ended September 30, 2001, as compared to the
year earlier period, despite the 17% decrease in revenue.

General and administrative ("G&A") expenses were $750,747 for the three month
period ended September 30, 2001 as compared to $808,488 for the comparable
period of 2000, representing a decrease of 7%. G&A expenses were $2,385,766 for
the nine months ended September 30, 2001 as compared to $2,483,051 for the
comparable period of 2000, representing a decrease of 4%. As a percentage of
revenue, G&A expenses increased to 19% in the third quarter of 2001 from 16% in
the third quarter of 2000 and increased to 19% for the nine months ended
September 30, 2001 from 16% for the comparable period of 2000. Reduced
professional fees related to legal services and investor relations accounted for
most of the decrease, while other G&A expenses remained relatively constant.

Marketing and selling expenses for the three month period ended September 30,
2001 decreased $180,491 from the comparable period of 2000 to $930,651, a
decrease of 16%. Marketing and selling expenses were $2,920,285 for the nine
months ended September 30, 2001 as compared to $3,114,519 for the year earlier
period, representing a decrease of 6%. Reduced public relations and advertising
expenses comprised most of the decrease, while other marketing and selling
expenses remained relatively constant. As a percentage of revenue, marketing and
selling expenses increased to 24% for the three months ended September 30, 2001
from 22% in the third quarter of 2000 and increased to 23% for the nine months
ended September 30, 2001 from 21% for the comparable period of 2000. The Company
expects to continue to aggressively promote its drug testing services during the
remainder of 2001 and in future years in order to expand its client base.

Research and development ("R&D") expenses for the three month period ended
September 30, 2001 decreased by $13,876 from the comparable period of the prior
year to $115,216, a decrease of 11%. R&D expenses were $501,779 for the nine
months ended September 30, 2001 as compared to $347,438 for the year earlier
period, representing an increase of 44%. This increase was primarily due to
expenses related to applying for FDA 510k clearance for its assays for
marijuana, methamphetamines, cocaine, and PCP. The Company previously received
510k clearance from the FDA to market its opiate assay on December 11, 2000. As
a percentage of revenue, R&D expenses remained the same at 3% for both the third
quarter of 2001 and 2000 and increased to 4% for the nine months ended September
30, 2001 from 2% for the comparable period of 2000.

Other income for the nine month period ended September 30, 2000 included a
$200,000 legal settlement from a breach of contract dispute with a third party
administrator. The remainder of other income in 2000 and other income in 2001
primarily represented interest earned on cash equivalents and short-term
investments. While the yields on investment balances increased in the first
quarter of 2001 and decreased slightly in the second and third quarters of 2001
as compared to the comparable periods of 2000, interest income decreased due to
lower average investment balances.


                                    Page 10


During the three months ended September 30, 2001, the Company recorded a tax
provision of $90,150 reflecting an effective tax rate of 43.7% as compared to a
tax provision of $317,200 and an effective tax rate of 41.3% for the three
months ended September 30, 2000. During the nine months ended September 30, 2001
and September 30, 2000, the Company recorded tax provisions of $351,300 and
$1,180,900 representing effective tax rates of 43.6% and 41.2%, respectively.
The increase in the effective tax rate was due primarily to non-deductible

                         -------------------------------

At September 30, 2001, the Company had $2.7 million of cash and cash
equivalents. The Company's operating activities generated net cash of $1,592,608
in the nine months ended September 30, 2001. Investing activities used $582,217
in the nine month period while financing activities used a net amount of
$1,741,561 during the period.

Operating cash flows decreased $485,969 in the first nine months of 2001,
compared to the year earlier period. The reduction in net income for the first
three quarters of 2001 as compared to the year earlier period was the main
reason for this decrease. Also contributing to the decline in operating cash
flows was a small decrease in accrued expenses for the first nine months of 2001
as compared to a sizeable increase in accrued expenses for the first nine months
of 2001. These were partially offset by a decrease in accounts receivable and an
increase in deferred revenue for the nine month period ended September 30, 2001
versus a significant increase in accounts receivable and a decrease in deferred
revenue during the comparable year earlier period. The non-cash effect of
depreciation and amortization in the 2001 and 2000 periods was $960,093 and
$974,879, respectively.

Capital expenditures in the first three quarters of 2001 were $571,021. The
expenditures primarily consisted of new equipment, including laboratory and
computer equipment. The Company believes that within the next two years it may
be required to expand its existing laboratory or develop a second laboratory,
the cost of which is currently believed to range from $2 million to $4 million.

During the nine month period ended September 30, 2001, the Company distributed
$1,692,529 in cash dividends to its shareholders and repurchased a total of
22,000 shares for treasury at an aggregate cost of $80,363.

At September 30, 2001, the Company's principal sources of liquidity included an
aggregate of $2.7 million of cash and cash equivalents. Management currently
believes that such funds, together with cash generated from operations, should
be adequate to fund anticipated working capital requirements and capital
expenditures in the near term. Depending upon the Company's results of
operations, its future capital needs and available marketing opportunities, the
Company may use various financing sources to raise additional funds. Such
sources could potentially include joint ventures, issuance of common stock or
debt financing. At September 30, 2001, the Company had no long-term debt.
