I always recommend people stick with flower and home made edibles for safety sake. I dabbled in the stronger stuff, and it's nothing like how weed should feel. Insanely anxiety inducing.
Most of people's worst experiences I've been witness to have been with homemade edibles.
Edibles are a lot more work and deliberation, and can give much more varied experiences due to digestion and personal metabolism (there are suggestions of enzyme differences that can make a major difference too). I never suggest it without a full rundown full of details and warnings. I only bring it up because I can't in good conscience simply recommend smoking anything to somebody who might care about their lung health.
That said, I've seen and had some really bad experiences on some badly-dosed edibles, but it doesn't compare to the worst I've seen messing around with real concentrates. Overdoses aside, I've had friends graduate from flower to edibles to tinctures to BHOs and just end up imbibing hundreds of milligrams of THC a day, and the results are often chronic anxiety, hyperemesis, inability to sleep, paranoia, and intense withdrawal when you quit. People who say "it's just a plant, it's harmless" haven't seen the effects of extreme abuse, and that's coming from somebody who generally likes using cannabis.
In my state, every package of THC product must contain a label with test results for that batch, including percentage of THC. There are rumors from internet folk from other states saying test cheating is rampant, but I've never experienced an unexpectedly hot or weak batch.
