I've been dabbling in our cannabis stocks for about 6 months now. I put in around $25k which has grown to 65K so far. It's a little volatile and there's always cries of overvaluation, but there's money to be made for sure.
Currently holding WEED, FIRE, ATT, MARI, HVST
I'll likely dump my HVST/ATT/MARI holdings into HMMJ (cannabis index) after some nice legalization run-up gains.
As long as you understand it's a very speculative market, you can throw $5k at something and have some fun. :)
