What are the effects of sniffing lighter fluid? I recently had a friend sit in a car to listen to music and smell lighter fluid. He tells me he gets a high from this. What are the effects of doing this? I would appreciate this to educate my friend.

I have been reading some studies that state a correlation between the "religious experience" generated by the psilocybin in magic mushrooms and LSD, and an alleviation of body dysmorphic, obsessive compulsive, and other related disorders. I was wondering if this is anything being pursued, whether these effects have been proven, and how long the symptoms are alleviated for if this is the case. Are there any specific conditions that must be met in order to avoid a "bad trip"? I know people experiencing any kind of mood disorder are succeptable as such.

Recently, my boyfriend began injecting cocaine. I've noticed that he and his friends share their needles, but "clean" them first with bleach and water. Is this a valid way to avoid contamination?

1) I am wondering about the direct effects nitrous oxide has on the brain, and if it is a fallacy that it kills brain cells.

2) What are the health dangers of inhaling nitrous oxide? I have heard people say that it "kills brain cells," but no one seems to know how, to what extent, and what the resulting effects are. Since nitrous oxide is commonly administered as anesthesia, is there a safe way to consume it for recreational use? If the user controls her oxygen intake, do the harmful effects (if any) still occur?

I have a friend at school who quit smoking last year in January, and went back to it in October. I have no idea why, and he also started doing other drugs, such as smoking blunts, doing ecstasy, and taking steroids. The drug that I am worried about him doing the most is ecstasy, because it's a dangerous drug. Also, he is always talking about doing drugs. How can I help him? I still want him to be my friend. Please help. This is serious.
