     Re:  Registration Statement on Form S-8
 
Ladies and Gentlemen:

          We have acted as counsel to Medi-Ject Corporation, a Minnesota
corporation (the "Company"), in connection with a Registration Statement on Form
S-8 relating to the sale by the Company from time to time of up to 495,050 and
500,000 shares of Common Stock, $.01 par value, of the Company (the "Shares"),
initially issuable upon the exercise of stock options granted pursuant to the
Company's 1993 Stock Option Plan and its 1996 Stock Option Plan, respectively
(collectively, the "Plans").

          We have examined such documents and have reviewed such questions of
law as we have considered necessary and appropriate for the purposes of the
opinion set forth below.

          In rendering our opinion set forth below, we have assumed the
authenticity of all documents submitted to us as originals, the genuineness of
all signatures and the conformity to authentic originals of all documents
submitted to us as copies.  We have also assumed the legal capacity for all
purposes relevant hereto of all natural persons and, with respect to all parties
to agreements or instruments relevant hereto other than the Company, that such
parties had the requisite power and authority (corporate or otherwise) to
execute, deliver and perform such agreements or instruments, that such
agreements or instruments have been duly authorized by all requisite action
(corporate or otherwise), executed and delivered by such parties and that such
agreements or instruments are the valid, binding and enforceable obligations of
such parties.  As to questions of fact material to our opinions, we have relied
upon certificates of officers of the Company and of public officials.

          Based on the foregoing, we are of the opinion that the Shares have
been duly authorized and, upon issuance, delivery and payment therefor in
accordance with the terms of the Plans under which such Shares are issued, will
be validly issued, fully paid and nonassessable.

          Our opinion expressed above is limited to the laws of the State of
Minnesota.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

Dated:  January 24, 1997

                                       Very truly yours,


                                       /s/  DORSEY & WHITNEY LLP
