                       PSYCHEMEDICS CORPORATION ANNOUNCES
                                YEAR END RESULTS
                       FOURTH QUARTER EARNINGS UP BY 180%
                           DECLARES QUARTERLY DIVIDEND

Cambridge, Massachusetts, February 18, 2004 -- Psychemedics Corporation
(AMEX:PMD) today announced fourth quarter and year-end financial results for the
period ended December 31, 2003.

The Company's fourth quarter revenue was $3,904,867 versus $3,362,081 in the
fourth quarter of 2002. Net income for the most recent quarter was $364,659 or
$0.07 per share compared to $130,461 or $0.02 per share for the same period in
2002. Revenue for the year ended December 31, 2003 was $15,995,256 versus
$16,068,130 for all of 2002. Net income for the year ended December 31, 2003 was
$1,218,270 or $0.23 per share compared to $1,255,700 or $0.24 per share in 2002.
The Company also announced a quarterly dividend of $0.08 a share payable to
shareholders of record as of March 5, 2004 to be paid on March 19, 2004.

Raymond C. Kubacki, CEO said, "We continued to be negatively impacted by what
the New York Times called the "longest hiring slump in more than sixty years."
Unfortunately, fewer hires results in fewer drug tests since most of our testing
is pre-employment drug testing at this time. I am pleased that, in spite of
this, we are able to report increased revenues and earnings for the fourth
quarter and maintain our consistent and strong level of profitability."

Kubacki continued, "While there was reduced hiring, and therefore testing, at
companies across the board, we have continued to add new customers at a very
healthy pace. In 2003 we added new customers at approximately the same number as
in each of the previous four years. This is evidenced by the fact that our
revenue for 2003 decreased by less than 1% when compared to 2002, despite the
severely weakened job market. We believe that our large and diverse customer
base will allow us to record substantial growth when the employment market
improves and that our patented and FDA cleared hair test for drugs of abuse will
continue to be the "gold standard" in the industry.

Kubacki concluded, "Our balance sheet is strong with over $3 million of cash, no
long-term debt and approximately $3.8 million of working capital. Our directors
share our confidence in the future of Psychemedics and voted to pay our 30th
consecutive quarterly dividend. We believe in rewarding our shareholders and
remain committed to paying a dividend while our company grows."

Psychemedics is the world's largest provider of hair testing for drugs of abuse
with thousands of corporations relying on the patented Psychemedics drug testing
services. Psychemedics' clients include over 10% of the Fortune 500, some of the
largest police departments in America and six Federal Reserve Banks. The Company
has the only FDA cleared hair test for drugs of abuse.
