I just had to laugh at the stupidity of your so-called argument, which can be summarized as: "I am high all the time, but not schizophrenic, therefore dagga is safe." LOL! Really? You are basing your dagga-addled utterances on a sample size of 1? Seriaaas???  

This is like a smoker saying "I smoke and haven't got lung cancer yet. Ergo, cigarettes don't cause lung cancer." 

Thank you for proving that weed does, indeed, severely reduce one's mental abilities. Pffffffffffft.
