You can get some unbelievably strong pot nowadays. I've seen just over 30% THC by weight. That's absolutely insane. The buds were so dense you couldn't really squeeze them between your fingers. I guarantee you it was grown under CO2 and the like. I don't think it was over $15 a gram either WITH tax. Personally I smoke blends with CBD varieties that end up between 7-15% THC by weight.

Concentrates (hash oil) - also legal. Vaping concentrates can allow finer dosage control and by finer I mean smaller for medical purposes. If I'm going to smoke before 7pm because my mood went south, I want to take as little as possible. But if you think contemporary weed is strong, oh my god... people around here will do dabs, basically hits of hash oil vaporized off superheated glass, and by hits I mean a decent size little blob. I don't understand how people can do that, let alone every day. It's weaponized cannabis. I hadn't had quite such a singular experience with pot in a LONG time, let's put it that way.
