                       PSYCHEMEDICS CORPORATION ANNOUNCES
                        1ST QUARTER RESULTS AND DIVIDEND
                                NET INCOME UP 99%

Cambridge, Massachusetts, May 8, 2003 -- Psychemedics Corporation (AMEX: PMD)
today announced first quarter results for the period ending March 31, 2003. The
Company also announced a quarterly dividend of $.08 per share, which will be
paid on June 26, 2003 to shareholders of record June 12, 2003.

The Company's first quarter revenue was $3,657,567, up 3% compared to
$3,568,461 in the first quarter of 2002. Net income was $104,339 or $0.02 per
share, up 99% from $52,434 or $0.01 per share for the same period in 2002.

Raymond C. Kubacki, President and Chief Executive Officer, said, "The poor
employment situation made the first quarter very challenging for our Company.
The hiring rebound that was hoped for did not occur, in fact, over 500,000 jobs
were lost during the quarter and the Iraq war further complicated an already
dismal jobs situation."

Kubacki continued, "Given the realities of the drug testing market, we are
pleased to be able to report revenue growth and a substantial net income
improvement. Our new business has been robust. While business from existing
customers is down across the board due to the lack of new hiring, a combination
of revenue from new customers and careful expense controls have allowed us to
continue to grow. With over 2,600 customers, we are poised for rapid growth once
the employment situation improves. Until then we will continue to expend every
effort to add new customers, build our base



of business, operate efficiently and position our Company for the rapid growth
we expect with an improved economy."

Kubacki continued, "The Company's balance sheet remains strong with over $3
million of cash and no long-term debt. The dividend demonstrates the Directors'
confidence in the Company's future growth and their continued commitment to
rewarding shareholders."
