                  Re: Registration Statement on Form S-3
                  --------------------------------------
Dear Sirs:

     We have acted as counsel to Milestone Scientific Inc., a Delaware
corporation (the "Company"), in connection with the preparation of a
registration statement on Form S-3 (the "Registration Statement") filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Act"), to register the sale by certain selling stockholders of 2,274,976
shares of Common Stock, par value $.001 per share (the "Common Stock"), of the
Company.

     In this regard, we have reviewed the Certificate of Incorporation of the
Company, as amended, resolutions adopted by the Company's Board of Directors,
the Registration Statement, and such other records, documents, statutes and
decisions as we have deemed relevant in rendering this opinion. Based upon the
foregoing we are of the opinion that:

     Each share of Common Stock included in the Registration Statement has been
duly authorized for issuance and is now, or when issued upon exercise and
pursuant to the terms of the instruments which they underlie will be, validly
issued, fully paid and non-assessable.

     We hereby consent to the use of this opinion as Exhibit 5A to the
Registration Statement. In giving this opinion, we do not hereby admit that we
are acting within the category of persons whose consent is required under
Section 7 of the Act or the rules and regulations of the SEC thereunder.

                                     Very truly yours,

                                     /s/ Morse, Zelnick, Rose & Lander, LLP
                                     --------------------------------------
