This letter will constitute an opinion upon the legality of the sale by United Cannabis Corporation, a Colorado corporation (the “Company”), of up to 5,000,000 shares of the Company’s common stock.

We have examined the Articles of Incorporation, the Bylaws, and the minutes of the Board of Directors of the Company, and the applicable laws of the State of Colorado and a copy of the Registration Statement.  In our opinion, the Company is authorized to issue the shares of stock mentioned above and such shares, when issued, will represent fully paid and non-assessable shares of the Company’s common stock.

Very truly yours,
