FOR IMMEDIATE RELEASE

            MEDTOX RECEIVES PATENT FOR "On-Site Drug Testing Method"
                      UPDATE ON POC DEVICE AND SYSTEM SALES

     ST.  PAUL,  Minn.,  June 13,  2002-  MEDTOX  Scientific,  Inc.  (AMEX-TOX),
announced  today that the United States Patent and Trademark  Office  granted to
MEDTOX a business method patent for its on-site drug testing method, U.S. Patent
No. 6,376,251. According to the abstract for the patent:

         "The invention described herein includes a method of testing an analyte
such as urine to determine whether the analyte contains specific substances such
as drugs of abuse. An on-site screening test provides a preliminary test result
either by visual or machine analysis of a screening test device, and the result
and user data are entered on a provided form. An electronic image or the form is
sent to a central data location, where it is received and the data on the form
is recognized by machine and stored, if the on-site screening test provided a
nonnegative result a sample is sent to a laboratory for further testing, and if
the test provides only negative results no further testing is done. The testing
laboratory performs further testing for verification of nonnegative screening
test results, and all data is collected at the central data location. Results
are then reported to the client or whoever the client designates to receive test
results."

         MEDTOX believes this patent to be a significant addition to its growing
intellectual property portfolio. Currently, there are approximately 25 million
laboratory screens for drugs of abuse (DAU) performed annually in the workplace
market. In 2001 MEDTOX performed over 2 million of those lab based DAU screens.
         Dick Braun, MEDTOX chief executive officer, said, "In the last three
years we have seen an increasing transition from laboratory screening for
workplace DAU to on-site or point-of-collection (POC) screening with disposable
devices.
         "In 1998 MEDTOX identified the potential for this transition. We then
developed a method to replicate and improve upon the controls and data
management of the laboratory model in a POC model-the PROFILE-II(R) Test
System(TM). The growing transition to POC screening will increase the value of
this patent to MEDTOX and its strategic partners. Additionally, MEDTOX is unique
in that it has both a federally certified laboratory and a POC device maker.
This allows us to provide a seamless transition for clients moving from one
model of screening to the other.
         "Delivery of the PROFILE-II(R) Test System(TM) is further enhanced by
WebTox(TM), MEDTOX's recently launched web platform and interactive program
management system. WebTox will set a new standard of customer service excellence
in our industry. By placing the power of information directly in the hands of
our customers, through the Internet, WebTox integrates point-of-collection
screening, and rapid laboratory confirmations with a feature-rich data reporting
and tracking system. WebTox provides customers with testing results and
tracking, chain-of-custody verification, supplies ordering capability,
statistical reporting, and sample collection site location information," Braun
said.

         MEDTOX also said that demand for its POC devices and on-site system
continues to increase. Device unit sales year to date through May since
introduction in 1999:

o        1999 sales through May        65,027   devices
o        2000 sales through May       287,691   devices
o        2001 sales through May       686,636   devices
o        2002 sales through May       968,729   devices

         "In addition to the growth in our POC device and system sales, MEDTOX
continues to have success in our esoteric clinical laboratory testing, pediatric
screening, and Clinical Trials Services. The Company is adding new laboratory
clients in the corporate drug testing market, an important trend since volume
from existing workplace clients continues to be negatively impacted by the
economy and lower levels of employment hiring. To support future growth MEDTOX
continues to increase investment in R&D, sales, and information systems," Braun
said.
         The patent contains 21 claims applicable to a system for screening
(testing) of other sample types in addition to urine, such as oral fluid, blood,
and serum. MEDTOX also believes the patent may have application beyond workplace
drugs of abuse testing. MEDTOX is currently working with its intellectual
property counsel to implement its strategic approach to maximizing opportunities
for itself and its business partners surrounding this patent. In addition to
patent protection for the on-site testing method, the United States Copyright
Office has issued a registration for MEDTOX's copyright in materials relating to
the method. MEDTOX has sought the broadest protection possible for its
proprietary on-site testing method.
