I feel like something that could help would be a limit to the potency. I like weed - but I really just want a 5-10% THC flower with some CBD in there for good measure (still not convinced the CBD isn't a placebo, but it's there naturally so no harm in having it). But most shops near me don't sell anything less than 20% THC. WTF?
Occasionally I can get something 10-15%. And if I'm lucky I can get something less than 10%.
Then look for high-CBD strains. The weed plant that produces lots of CBD will not produce much THC. The inverse is also true. I see CBD strains all the time that are as low as 1% THC.
Yes that's usually what I do. But I think in general the average potency at stores encourages people to do too much. It did for me when I first moved to a legal state. I had no idea what I would enjoy and just expected that the average THC content was a mid-level intensity. In reality it's at the top end.
