Jim Cramer Weighs In On McKesson, Mazor And MGM Growth Properties

On CNBC's "Mad Money", Jim Cramer said margins for opiate companies are going down. He would stay away from McKesson Corporation MCK and other opiate companies. He would own UnitedHealth Group Inc UNH.

Cramer likes Mazor Robotics Ltd - ADR MZOR and he sees more room on the upside.

MGM Growth Properties LLC MGP is trading lower because it's a play on the yield curve and interest rates, explained Cramer.
