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?

My friend recently smoked some pot laced with cocaine. First of all, is this possible? Whatever the case may be, he seems to be infatuated with the idea of trying straight coke. I've heard that trying coke for the first time is quite dangerous, true? Also, what are the effects of the high? And how detrimental is coke in general?

Could you possibly tell me the interactive effects of Zoloft (the anti-depressant) and MDMA (Ecstasy)?

I have been a smoker for about 8 years and smoke about a pack per day. I am also an alcoholic and now drink about 7 to 10 beers a day, and have been for the past 2.5 years. Last night I decided to quit drinking beer every day and today I am already shaky, nervous, and can't concentrate. I want to quit smoking also so I can join the army. Is it dangerous to quit both at once? Would it be too much stress on my body and mind? And also, would having just one beer a day for the next couple days help with the withdrawal symptoms?

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?

I have a very addictive personality. Fortunately, I am married and have a family and because of the added responsibility of taking care of my family I stay away from a lot of the harmful vices. However, for some stupid reason I decided to try out nicorette. I quit smoking about 12 years ago and thought I would just try out nicorette to see if I could get a buzz. Well two years later I am totally hooked on the stuff and wondering if I should start smoking/chew/patch to get off the stuff. How bad is nicorette for you and is it better than smoking?

My dad requires me to take weekly drug tests since he found out that I was smoking marijuana. My first test came back positive for marijuana and cocaine. I was not surprised about the marijuana because I had only been clean for five weeks, but I have never done cocaine. Is there anything that could have triggered a positive result? Could opium or mushrooms or any other drug possibly trigger this positive result?

1) I found a white powder in my friend's car and I think it might be cocaine. I'm not sure if it is or not. I don't know if I should confront him with it or what I should do. I don't want to see my friend get hurt, but if I'm wrong, I don't want to falsely accuse him of something like this. How should I go about handling the situation?

2) I am a first-year business student and have a little sister who is a junior. I think she is doing cocaine because I found some "paraphernalia" in her room last week. What can I do without damaging my relationship with her?
