I’m going to take a pass on answering that question! The reason has nothing to do with morality. It’s just that the existing companies’ stocks have soared since they came public. It’s hard to create a sensible “valuation” for them — although obviously the potential seems enormous. But the stock already reflect that!
And despite increasing legality in many states for both medicinal and recreational use — there is a big question about “banking” for these companies — since the use of marijuana is still illegal on a NATIONAL level. And since most banks are chartered nationally — making it impossible for them to handle financial transactions for these companies.
I personally tend to avoid speculating amidst so much uncertainty. And I may have to eat those words — or smoke them! — sometime in the future!
