I Have A Friend Who Is Showing Signs Of Being

Question: I have a friend who is showing signs of being addicted to smoking marijuana. He gets anxious when he doesn't smoke. He is more aggressive and gets angry easily. He's depressed sometimes. He told me that marihuana is healthy and people cannot be addicted to it. He did research and he says it's impossible. Is there any side effects to smoking marihuana?

Thank you for the information. He did get psychotic breaks. I remember he got it in the first few days he started smoking and because he follows the Bible and is very religious when it come to the Bible teaching. He uses that excuse for smoking. He called me and other people demons, curse people in the name of Jesus. It is hard to say something against someone who has such strong religious beliefs and uses that against his addiction. But he still gets psychotic breaks. Last time he told me to only way he is going to read something bad about marihuana use is if I had solid proof and backed up with doctors. So if you have any official addiction site about specifically marihuana, that would be so useful. I don't believe that it is going to help right away but it is going to give him something to think about and maybe he can start realizing that there may be a problem. Thank you
