It's really a gamble because this is uncharted territory. The most popular ones are CBIS, HEMP, MDBX, and PHOT. I had never played the stocks before but two months back, I decided to buy into ENDO, which holds the intellectual rights to CBIS and has agreements to have products sold via Medbox (MDBX). I bought in at .06 a share. Two weeks later, it was up to .17 a share. I decided to hold out and now it's back down to .07 again. Meh. Now, I'm just patiently waiting while keeping my finger on the pulse of the mmj industry. I think good things will happen if the company ends up releasing product lines. Until then, who knows?
