Is there any validity on the use of marijuana to treat the anxiety and physical tics such as handbitting and headbanging in adults with Autism? It has to be just as valid or even safer than using benzodiazapines and other "downers" over the long term.

I saw an article online somewhere called "Why I am Giving my 9-Year-Old Autistic Son Pot". I don't remember all the details but this is one of many cases where it has been used to treat autism. I'm sure if you googled it the article would come up. Marijuana doesn't cause any kind of physical or neurological dependency (only psychological – although you can get psychologically addicted to anything). You can get addicted to benzos. I've never puked because I didn't get to smoke my bowl but people get sick when they don't get their benzos.

I think you should watch a British documentary called 'the evil weed'. Basically, (if it's legal where you are) you need to buy some that is low in THC as THC will make anxiety a whole lot worse. If used pure, it should not cause any harm but remember everyone reacts differently to it.

I just use it recreationally.
