I'm interested in this-- cool topic.
If I invested, id try a few "penny stock" companies and then try a few higher cost that I personally like. I never go to dispensaries but I could see there being a lot of very commercialized ones that aren't really all that good. But then again some people don't really care that much
Investing in a small time higher quality dispo I do not think would be good profit until it turns into a bigger sized company, which would result in poorer product.
