      Re:   Registration Statement on Form S-8 to be filed with the Securities
            and Exchange Commission dated August 17, 2005
            --------------------------------------------------------------------

Gentlemen:

      We have acted as counsel to Micro Bio-Medical Waste Systems, Inc., a
Nevada corporation, (the "Company") in connection with the preparation and
filing with the Securities and Exchange Commission under the Securities Act of
1933 of the Company's Registration Statement on Form S-8 relating to 500,000
shares of the Company's common stock, par value $.001 (the "Shares"), pursuant
to the Company's 2005 Stock Compensation Plan.

      In connection with that registration, we have reviewed the proceedings of
the Board of Directors of the Company relating to the registration and proposed
issuance of the Shares, the Certificate of Incorporation of the Company and all
amendments thereto, the Bylaws of the Company and all amendments thereto, and
such other documents and matters as we have deemed necessary to the rendering of
the following opinion.

      Based upon that review, it is our opinion that the Shares, when issued in
conformance with the terms and conditions of the Plan, will be legally issued,
fully paid, and non-assessable. We do not find it necessary for the purposes of
this opinion to cover, and accordingly we express no opinion as to, the
application of the securities or blue-sky laws of the various states as to the
issuance and sale of the Shares.

      We consent to the use of this opinion in the registration statement filed
with the Securities and Exchange Commission in connection with the registration
of the Shares and to the reference to our firm under the heading "Interests of
Named Experts and Counsel" in the registration statement.
