My girlfriend tells me she uses marijuana to calm herself if she is having a stressful day. She has been doing this for many years. She says smoking pot is like self-medicating — it is better than using anti-depressants. She also claims smoking pot helps with depression because of how it helps produce serotonin in the body. What is serotonin and how does it help depression? Does smoking pot really help with managing your anxiety, depression, etc.?

I really want to try pot because I am SICK of being uptight and careful all the time. I have been depressed and anxious for several years and I just want to feel SOMETHING different. But I've had a couple of panic attacks (both related to medication) and they were the most frightening things I've ever experienced. I'm scared that pot would do the same thing to me. What do you think? I know you can't encourage me to smoke pot but I would very much appreciate an honest answer, which I know you always give. (I know that smoking pot is not the best thing to do when you have depression and anxiety, but it would only be once, and I would be with friends. By the way, I'm not currently on medication as I find it useless. But I'm not trying to self-medicate. I just want to remember what it's like to experience an emotion that is not depression or anxiety). Thank you very much.

Is it possible to die from a pot overdose?

I typically don't smoke that much weed, especially during the school year. Last year, for instance, I smoked maybe once a month. This summer, though, my friends and I have all hit the bong pretty hard. I'm worried such frequency over a few months could impair my long-term capacity for learning. Is there any salt to this concern?

I recently went to a new psychiatrist and he requested a blood test. I was wondering what he was ordering a blood test for, so I asked him and he said many things. I was wondering if he is testing me for drugs? I am not a huge smoker (marijuana). But I do smoke usually multiple times a week, and did not feel the need to share that with my doctor yet. Could you tell me what they are testing me for?
