Gummies are about as potent as dime-store candy, sad to say.
Equally sad, in the bud market, 40% THC or higher is hard to find. I guess I just got lucky finding "Rock Candy," which my dispensary here in Calgary, Alberta, always has in stock. I have seen a few strains come in in the high forties, but at the time I wasn't yet wise to the game.
Even so.....none of the commercial, legal pot strains grown these days come anywhere close in freakout power to the mind-blowing weed I and my adolescent friends toked in the Sixties. Now THAT weed was The Real Thing! (But illegal.)
