Nope, canadian companies aphria and aurora tried that and almost lost their places on the stock exchange. Rules around pot are the most stringent and bizarre I have ever seen. They can cooperate on branding but products are kept in playpens. International trade is totally off limits. Heck can you imagine if cocacola had to grow their sugar cane, build a factory to bottle bottle and distribute only in one state? Can not take the bottles across state lines? Build a brand new sugar grow, factory and distribution system in each state? Crazy huh? That is american weed!
