But can you buy stocks in marijuana if you live in an illegal state and you want the stock from a legal state?
Rec cannabis is illegal in the USA, period. You'd be investing in a company that may or may not be doing business in a legal state, and may or may not be medical. You can buy what ever you want, and it wont change those simple facts. Cannabis stocks are very high risk stocks. Be prepared to lose, if you gamble in this manner. GL
