                       PSYCHEMEDICS CORPORATION ANNOUNCES
                              2ND QUARTER RESULTS,
                                DIVIDEND DECLARED

Cambridge, Massachusetts, August 5, 2003 -- Psychemedics Corporation (AMEX: PMD)
today announced second quarter results for the period ending June 30, 2002. The
Company also announced a quarterly dividend of $.08 per share, which will be
paid on September 19, 2003 to shareholders of record on September 5, 2003.

The Company's second quarter revenue was $4,266,767 as compared to $4,792,903 in
the second quarter of 2002. Net income was $398,781 or $.08 per share versus
$638,294 or $.12 per share for the same period in 2002.

Raymond C. Kubacki, President and Chief Executive Officer, said, "During the
quarter we struggled with a difficult drug testing environment. The employment
picture, that some say is the worst in 20 years, has made it a difficult time
for our industry. Since pre-employment drug testing is our major business, our
results continued to be adversely affected. The good news, however, is that we
were able to continue to add new accounts at a healthy pace and to demonstrate
our ability to produce strong profit margins in a tough environment. We remain
optimistic, however, that an improved employment market will allow us to record
significant growth and that our patented and FDA cleared hair test for drugs of
abuse will continue to be the "gold standard" in the industry."

Kubacki continued, "The dividend demonstrates the Directors' continued
commitment to rewarding shareholders and sharing the overall financial success
of the Company with

them. The Company's balance sheet is strong with over $3 million of cash and no
long-term debt."

Psychemedics is the world's largest provider of hair testing for drugs of abuse
with over 2,600 corporations relying on the patented Psychemedics drug testing
services. The Company has the only FDA cleared hair test for drugs of abuse.
