                  Note Receivable - Parent represented a demand loan made to
                  Substance Abuse Technologies, Inc., formerly U.S. Alcohol
                  Testing of America, Inc. (the "Parent" or "SAT"), a publicly
                  traded company, which was due on or before December 31, 1996.
                  The note bore monthly interest at the rate of 8% per annum.

NOTE 6 -         Commitments and Contingencies

                 In June 1995, the License Agreement with the Department of the
                 Navy was renegotiated and amended to provide for minimum annual
                 royalties of $100,000 per year commencing October 1, 1995 and
                 terminating September 30, 2005. Additional royalties will be
                 paid pursuant to a schedule based upon sales of products. The
                 Company sub-licenses this agreement from its Parent and,
                 accordingly, has obligations to its Parent for the royalty
                 payments required by the License Agreement.

NOTE 7 -         Registration Statement

                 During May 1996, SAT filed a Registration Statement on Form S-4
                 under the Securities Act of 1993, as amended, in an attempt,
                 through a consent solicitation, to acquire the common stock of
                 the Company owned by the minority interest and thereby own 100%
                 of the Company's common stock. There can be no assurance that
                 such solicitation will be successfully completed.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS


LIQUIDITY AND CAPITAL RESOURCES

     The Company is a development stage enterprise with no earnings history and
initially derived its capital resources from unsecured advances provided by SAT.
During October and November 1993, the Company sold 1,721,900 shares of its
common stock to the public at $5.00 per share and netted approximately
$7,099,000. From the net proceeds of the offering, the Company repaid the
advances made by SAT.

     During the period ended December 31, 1996, the Company had outstanding
loans in the amount of $1,200,822 payable to the Parent to fund continuing
research and development. These advances are evidenced by notes due after the
results of the consent solicitation for the proposed acquisition of the U.S.
Drug shares owned by its minority interest are known. These advances bear
interest at the rate of 8% per annum at December 31, 1996. SAT has committed to
advance a total of $1,500,000 to the Company to fund continuing research and
development. The Company is dependent on continuing advances from its Parent to
continue the research, development and ultimate marketing of its products and to
fund its working capital requirements for the next twelve months.

     The Company completed a feasibility study in November 1996 as to the saliva
based drug testing products and made a decision to proceed with development. The
Company estimates that it will be approximately two years before the drug
testing products will be available for marketing. There can be no assurance that
the Company will successfully complete its development program on a timely
basis, that it will thereafter obtain the necessary governmental approval or
that marketing will start when contemplated.

     U.S. Drug will require approximately $10,000,000, in addition to the
approximately $8,300,000 already expended, to complete development of a saliva
based testing products. Although U.S. Drug management believes that its parent,
SAT, can raise the necessary funds to complete this project, failure to raise
the funds will result in cessation of operations of U.S. Drug because it has no
other product to market or service to furnish.
