Need Info About Investing In Weed

I am working on a 600-700 word story about investing in marijuana and would like to interview someone –preferably via email– who can shed some light on the kinds of weed businesses investors might consider if they’re looking make what some might consider a risky financial move. 1) Which businesses/stocks are doing well? 2) Which are too risky to consider given the current political climate? 3) How can interested investors start the process?
