                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

                                  June 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 six months
ended June 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 Standards ("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                      Six Months Ended

For the three months ended June 30, 2001 and 2000, options to purchase 1,352,370
and 834,370 common shares, respectively, were outstanding but not included in
the diluted weighted average common share calculation as the effect would have
been antidilutive. For the six months ended June 30, 2001 and 2000, options to
purchase 1,087,870 and 1,096,070 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


                                     Page 7
   8


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 June 30, 2001 and December
31, 2000, the Company had deferred revenue balances of approximately $733,000
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 six month
periods ended June 30, 2001 and 2000 was the same as reported net income.

5. Computer Software Costs

As of June 30, 2001 and December 31, 2000, $1,205,540 of software development
costs have been capitalized. For both of the three month periods ended June 30,
2001 and 2000, $60,294 of related amortization was charged to operations. During
both of the six month periods ended June 30, 2001 and 2000, $120,588 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, as amended by SFAS No. 138, 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 adoption of these statements did not have a
material impact on the Company's financial position or results of operations. As
of June 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.

patented hair analysis method involving radioimmunoassay technology to analyze
human hair to detect abused substances. The founder of the Company has granted
to the Company an exclusive license to all his rights in this hair analysis
technology, including his rights to the drug extraction method.

                              RESULTS OF OPERATIONS

Revenue was $4,518,430 for the three month period ended June 30, 2001 as
compared to $5,472,701 for the comparable period of 2000, representing a
decrease of 17%. Revenue for the six month period ended June 30, 2001 was
$8,582,753, a decrease of 15% from the $10,154,728 of revenue reported for the
comparable period of 2000. Although the Company added new customers in the first
two 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 current economic downturn as many clients
experienced deep reductions in their new hires and the number of their drug
tests.

Gross margin was 56% of sales in the second quarter of 2001, as compared to 57%
in the second quarter of 2000. Gross margin for the six months ended June 30,
2001 was 53% of sales, as compared to 56% for the six months ended June 30,
2000. The decrease in margins from the year earlier periods were caused by fixed
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 achieve a gross margin reduction of only
1% for the second quarter, as compared to the year earlier period, despite the
17% decrease in revenue.

General and administrative ("G&A") expenses were $811,040 for the three month
period ended June 30, 2001 as compared to $890,803 for the comparable period of
2000, representing a decrease of 9%. G&A expenses were $1,635,019 for the six

months ended June 30, 2001 as compared to $1,674,563 for the comparable period
of 2000, representing a decrease of 2%. As a percentage of revenue, G&A expenses
increased to 18% in the second quarter of 2001 from 16% in the second quarter of
2000 and increased to 19% for the six months ended June 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 June 30, 2001
decreased $67,298 from the comparable period of 2000 to $955,313, a decrease of
7%. Marketing and selling expenses were $1,989,634 for the six months ended June
30, 2001 as compared to $2,003,377 for the year earlier period, representing a
decrease of 1%. Expenses pertaining to additions to the sales force related to
the corporate market were offset by reduced public relations and advertising
expenses in the first and second quarters of 2001, as compared to the first and
second quarters of 2000. As a percentage of revenue, marketing and selling
expenses increased to 21% for the three months ended June 30, 2001 from 19% in
the second quarter of 2000 and increased to 23% for the six months ended June
30, 2001 from 20% 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 June
30, 2001 increased by $104,371 from the comparable period of the prior year to
$215,801, an increase of 94%. R&D expenses were $386,563 for the six months
ended June 30, 2001 as compared to $218,346 for the year earlier period,
representing an increase of 77%. 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 increased to 5% in the second quarter of
2001 from 2% in the second quarter of 2000 and increased to 5% for the six
months ended June 30, 2001 from 2% for the comparable period of 2000.

Other income for the six month period ended June 30, 2000 included a $200,000
legal settlement from a breach of contract dispute with a third party
administrator. The remainder of other income 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
quarter of 2001 as compared to the first and second quarter of 2000, interest
income decreased due to lower average investment balances.

During the three months ended June 30, 2001 and June 30, 2000, the Company
recorded tax provisions of $238,800 reflecting an effective tax rate of 42.1% as
compared to a tax provision of $477,700 and an effective tax rate of 41.3% for
the three months ended June 30, 2000. During the six months ended June 30, 2001
and June 30, 2000, the Company recorded tax provisions of $261,500 and $863,700
representing effective tax rates of 43.6% and 41.2%, respectively. The increase
in the effective tax rate was due primarily to non-deductible expenses for tax
purposes.

                         LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2001, the Company had $2,809,559 of cash and cash equivalents. The
Company's operating activities generated net cash of $1,177,646 in the six
months ended June 30, 2001. Investing activities used $564,027 in the six month
period while financing activities used a net amount of $1,238,653 during the
period.

Operating cash flows decreased $298,987 in the first six months of 2001,
compared to the year earlier period. The reduction in net income for the first
two quarters of 2001 as compared to the year earlier period was the main reason
for this decrease. This was partially offset by the net effect of a smaller
increase in accounts receivable, an increase in accounts payable and a smaller
increase in accrued expenses during the first six months of 2001 as compared to
the first six months of 2000. The non-cash effect of depreciation and
amortization in the 2001 and 2000 periods was $645,087 and $680,646,
respectively.

Capital expenditures in the first two quarters of 2001 were $552,830. 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 six month period ended June 30, 2001, the Company distributed
$1,269,203 in cash dividends to its shareholders.

At June 30, 2001, the Company's principal sources of liquidity included an
aggregate of $2,809,559 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 June 30, 2001, the Company had no long-term debt.
