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.

I used to be a heavy ecstasy user and now am clean from ecstasy. I find I can't ejaculate. Alice, I guess my question is would the ecstasy have affected me sexually, so that I can't ejaculate when I'm having sex?

I have a huge dilemma. I have an addiction to a certain drug that has turned my life upside down. That drug is crack cocaine. The worst part about it is that nobody knows this but me. Nobody knows that right now, my life is on the brink. How do you express this problem to people who don't even have a clue as to what you are dealing with? How do you reach out to the people who you love and trust when you are so ashamed of the truth? One thing that I do know is that I'd better do something fast because if I don't, I will lose my fight with life. HELP!!

I have been trying to find information about the hope for recovery for previous meth users, but there doesn't seem to be a consensus. Some sources say that meth causes permanent damage to the brain, while others are a little more hopeful and say some important brain functions might recover.

I used meth about fifteen times, which I gather isn't a lot in comparison to other meth users but is still a considerable amount. For a while I have felt paranoid and anxious and it has been more difficult to perform daily tasks and just generally think straight. Also, things I used to enjoy are not really that enjoyable anymore.

My question is, will I be able to have my brain back? If so, how much of it? Will I ever go back to being my old self?
