How do I buy Trulieve and other American pot stocks?

I'm deep into APHA/TLRY and I believe in their international potential but I'd really like to make a play into American stocks, specifically before they get listed on the NYSE and shoot for the moon. Is that even possible for someone with only, say, $3000 dollars to put down initially? How would I do that? Or do I just need to wait and miss out on some of the potential gains?
