Its propaganda and fake, the amount you would need to consume for a lethal dose of THC is astronomical. You would green out before you could smoke or vape that much. You would puke, and pass out before you could eat enough.
Fake as fuck, I've been so high before I thought I was gonna have a heart attack, but I was just tripping haha it can't kill you or anyone it's safe so smoke on people My eyes are shut...I'm just getting started!
