There is marijuana rehab centers located all over the place. It's just not a common thing, and most of the detox patients are being forced to go by their parents (ages 14-17 mostly). I have heard of them before, so they are out there.

I agree somewhat though. You watchg tragic stories or read about them, and none of them are because of cannabis. They are over the harder drugs. Cannabis rehab is uncommon, but ask some of teenagers that have strict parents here. Some of them have been sent to rehab for cannabis.

There are rehab centers for video game addictions. Doesn't get much lamer than that, and the sad part is, 95% of the patients are males.

"You're in here, for some marijuana?! That's bullshit!"
"Marijuana isn't an addiction. I used to suck dick for coke. You ever suck some dick for marijuana?"
"Huh!? Boo this man"
"BOOOO!"
