Sold as harmless. It isn't, and you've probably already seen why.
You already know how this can go for somebody. The friend who got deep into dabs or carts and slowly drifted somewhere you couldn't follow: paranoid, flat, sure of things that weren't real, gone quiet in a back bedroom. Maybe they came back. Maybe they didn't. Anyone who spends real time around heavy weed has watched some version of it, and has had the same quiet thought: not me.
That wasn't bad luck or a weak mind. It was the drug, and specifically how strong the drug got while nobody was paying attention. This is about what today's weed actually does to some of the people who use it, and why the ones it hits hardest are young.
You've got a good instinct for sniffing out a scare on this subject, and you'll want it here, so this won't preach and it won't exaggerate. It's short, about twenty minutes, and every number links straight to its source, so you don't have to trust me; you can check. The honest facts are unsettling enough without any help.
One thing worth knowing going in: almost everything you've absorbed about weed being basically fine came from people with something to sell. A legal industry spent a fortune making sure you'd never stop to ask what the strong stuff does. That's the story this checks. It's for people who use, people thinking about starting, and the people who love them.
Read it, then make up your own mind — with the actual evidence in front of you, instead of whichever version someone with a sales target picked for you.
