I have heard doctors say that if you smoke 3 or more joints a week, you are stoned all the time...as in, there is always MJ in your system if you smoke that much, but who knows for sure.

They say if a cocaine user uses 1gram of cocaine a day, there are considered an addict, but it could be different for marijuana
Nochowderforyou Reviewed by Nochowderforyou on . What is classed as heavy use? They keep bringing out studies on how cannabis effects teenagers. Saying that being a heavy cannabis smoker leads to psychosis and other mental illnesses. The question I have is what is classed a heavy user? An ounce a day? An ounce a week? What are they baseing there "facts" on? Rating: 5
