They actually have a drug detox place that you camp there and they treat you with a lot of weed. I wouldn't recommend it but i seen it halped some. I was sober 2 years before i started smoking again.

I live in Colorado. I don't need to go to a special place to get weed for kicking other shit. In my city (Denver), there are more weed shops than McDonald's, Wendy's, and Starbucks combined.
Some addicts when they are getting clean they have to be away. Not everyone can kick stuff just at home. I tried with just weed a bunch of weed and nahhh it wasn't working.
