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 want to know what it is when you spontaneously trip without dropping tabs or anything. I've never had any drugs except marijuana. It is weird. I know that tripping is an induced psychosis, so am I psychotic or what? I was seeing a shrink and will be going back into treatment next semester. I think substance use is boring and a complete copout on life. I've made a lot of discoveries without needing to trip. Why does this happen? Tell me what you know.

I have been doing weed for about six months now and on occasion a few other drugs. I usually do it only on average three times a week and a lot more on the weekends. I feel that it is ruining my life because my concentration is terrible and my marks have dropped significantly (20 points). I feel like I'm in a dream all the time and it just isn't fun anymore. I have heard that pot is not addictive but I have tried to stop but I feel sick and irritable if I don't smoke up. I have realized I need to quit but I can't. Why can't I stop if this "soft drug" is not addictive? Am I crazy? Please help. I want my life back. Thank you so much.

Is it harmful, under any circumstances, to eat marijuana instead of smoking it?

I smoke hookah on occasion, but am not a regular hookah smoker. Recently some of my friends have expressed interest in smoking hookah but are concerned about the health side effects; needless to say, for very legitimate reasons. However, non-tobacco shisha, made simply of herbs and molasses, claims to be a healthier alternative to regular shisha that contains tobacco. Though I can assume it is not without its shortcomings, is it still healthier then regular tobacco products, as it claims?

I know all the effects smoking has on the body, but nobody seems to have information on what it does to your sex life. What are the effects, like dryness, de-sensitivity in areas, etc? If I quit, would sex be better?

My friends and I occasionally (once a week or so) like to smoke the "Hookah" or sometimes referred to in Arabic as an "argeelay." The tobacco that it comes with smells really good and comes in all kinds of flavors, such as apple, mango, mixed fruit, etc. Anyway, I consider myself to be pretty healthy in that I have never experimented with drugs, never smoked cigarettes, and rarely drink alcohol. My question is about the health effects of smoking a hookah. The rewards are mostly relaxation after a long day of studying for law school. The hookah provides this through smell, flavor, and sound of the water that filters the tobacco when you puff on it. However, I don't know what the health risks are. How does it compare to cigarettes? People say that it's much safer than cigarettes... and according to the packaging that comes with the tobacco, there are far fewer harmful ingredients... in fact, it's mostly tobacco and molasses. It's a very popular trend these days. It's time we get a good source of information. So what's the verdict?

I only smoke occasionally. I smoke when I go out to clubs, etc. (once or twice a week). I smoke about ten cigarettes each time. Is this likely to have an impact on my health?
