I believe the risks of cannabis are significantly less than nearly every other recreational drug out there. Hell, I am a huge psychedelic proponent, which in many cases causes less physical damage than most other drugs but also comes with its own list of caveats.
But yeah, I see what you are saying and agree. It is important to understand the correct risks of just about anything in life.
Some dry alcoholics love their soapbox though. I'll occasionally bash alcohol, but I honestly try to keep my opinion to myself unless I am with other recovering alcoholics. (Repetitive negative reinforcement has a place, believe it or not.) What I am saying is that it is easy for someone in perpetual recovery to get a hair preachy. It's a thing. (Also guilty here, btw.)
