I have been shooting cocaine steadily for almost two months now and want to know what the difference between the physical and emotional addiction is. I am not sure if I have been experiencing withdrawals, but I feel sick a lot lately. I know shooting heroin has made me sick before. Can cocaine eventually make you dope sick as well?

The new acid like synthetic club drug "Foxy" has caught the attention of a few of my friends and I am wondering what kind of high it is — compared to LSD — and what kinds of damage it does to the brain?

I recently performed oral sex on a guy who had been using crack cocaine. He had been using for about three days straight. When he climaxed, I swallowed his semen and about ten minutes later, I felt very dizzy and pretty much high. He probably ejaculated about two to three tablespoons worth.

Is it possible that the hardcore drugs he had been doing that week pass through his semen? If so, does this happen with every drug?

And, if so, if I were to get drug tested, would it show up?

I would appreciate any answers you can provide.

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?

My boyfriend is on steroids. He injects them through his rear end. I have seen no negative signs of this but I have read about them and I am worried that extended use of this drug will lead to serious problems, emotional and physical. I have told him about the problems steroids cause, but he doesn't think it will happen to him. What could I do to stop his use?

I am a freshman on a collegiate varsity sports team. Team gatherings, when we are not practicing, usually consist of excessive drinking with and without drinking games. I did not drink in high school and when I tried drinking with the team it made me feel really sick. I want to bond with my teammates (they are really great when not drunk) but I don't know how because if I am the only guy in the room not drinking I can't play drinking games with them, discuss favorite types of alcohol, or even carry on a real conversation because at a certain point in the night they stop forming coherent sentences. I need to be friends with this group of people but I would like to do so in a way that allows me to remember the night in the morning. Is this possible? What should I do?

While I don't really approve of their lifestyle (why devote six days a week to practice only to reduce your performance with alcohol?), I make no moral judgement. I don't want to change their way of doing things, I just want them to respect my way.

I never get hungover, yet I am a light female. You guys say that this is a sign of a serious problem, please explain.

1) I have had acid coming up my throat from my stomach for the last 3 weeks. It comes up and just burns my throat. What is it? Do I have an ulcer? By the way, I get 3 hours of sleep a night, and my roommate doesn't help the situation.

2) I have recently asked you about my would be ulcer. I shall pose the question again. Lately I have this damn acid coming up my throat. I've been under a lot of stress and have strange sleeping habits. I am also drinking a lot of coffee. I drink about 5 cups of coffee a day and my roommate isn't exactly stress relieving. I go to bed about 3:30am and wake up about 5:45am for crew. Am I dying? Do I have an ulcer? What's wrong with me?

A couple of questions for you: what are the long-term side effects of one abusing prescription painkillers, such as Vicodin? What advice can you give to someone who has gotten off of them to help them stay off???

My friends take Pepcid AC when they drink to reduce the redness on their faces. Is this safe? I'm worried that it will hurt their stomach linings. Please help.

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?

1) Are there any adult children of alcoholics groups on campus?

2) My father is an alcoholic and I've been told that I should stay away from drinking altogether. I'm a freshman this year and it seems like most of my friends always want to go to keg parties or hang out and drink. Sometimes I drink with them, but then I feel guilty and worried afterwards as I think about my dad. It's hard to avoid alcohol here, but I don't want to follow in my father's footsteps either. Any advice or support you can give would help. Thanks.

1) I have two friends who I think are drinking too much. I don't know what to do. They are very defensive should anyone say anything to them about their excessive habit, and a lot of our friends are giving up on them. This has become a daily thing and their schoolwork and friendships are all suffering. They are both 21; one recently broke up with his girlfriend of several years and the other has been single for a while and he hates it. I know that has a lot to do with it. Please suggest some non-intrusive ways to help them. I'm really at a loss.

2) Last year, I became very good friends with a guy on my floor. He was a little out of the ordinary in the way he dressed, as well as in some of his opinions and habits. I had the feeling that he did drink more than he should, and he also did pot. I did not worry too much about it because it appeared to be more of a lifestyle choice than an addiction, and it did not cause him major troubles.

Unfortunately, he started to have academic problems. He did not do his work, missed classes, and eventually exams as well. I still did not relate these things to his alcohol and drug habits, and I hoped that once he got over the adjustment everyone needed to make in freshman year, he would be fine. Well, he wasn't. He did not come back to school this fall, and when I called him, I learned that he had gone through a lot that summer. He was diagnosed with depression and a cocaine addiction, put on Prozac, and sent to therapy. At that point, I thought that he was on the right track because he was also going to get a job and planning to take classes at a nearby college.

However, when he came to visit me a month later, he had already had two beers before he even came here and got more and more drunk as the evening progressed. I would not let him drive home, but he ignored my warnings and left anyway. I was very disturbed because a friend of his had just been in a drunk driving accident. I was very mad at him, told him clearly that I will always be his friend but prefer not to talk to him or see him if he showed up drunk again. He did not call for a while and neither did I. When he called me yesterday and I told him that I thought he should do something about his alcohol problem, he kept repeating his excuses, that he drinks because he is Irish, that he doesn't care if he dies early as long as he had fun in life, etc. On the other hand, he can't find a job and seems to be very depressed. I want to help him, but I don't know how. Any ideas?

My uncle shoots heroin. My father used to do cocaine. My moms' (both of them) used to smoke weed with their friends when I was eight. I smoked weed when I was twelve. I sold weed at 14.

I don't want to continue in the vein of my addictive family (no pun intended). How hereditary is addiction? What measures can I take to avoid falling into the same hazy trap of my family members?

I think it would be a good idea for me to stop smoking marijuana and cut down on my drinking, at least during the school year. The problem is, I have been doing it for so long it is almost as though I have forgotten how to have fun without it. Contributing to this problem is the fact that many of my friends smoke or drink to have fun. Many of my other friends just do not seem to have fun at all; they stay in Friday and Saturday nights to do work. I've found it difficult to quit, I think because I'm just not sure of what's out there to do that's fun without being stoned or drunk. Can you recommend anything that's fun whether you're intoxicated or sober, so that I don't have to stop hanging out with certain friends if I want to relax and have fun? I want to finally enjoy life without relying on an altered state of consciousness. What's there to do when you're sick of renting movies? Also, any tips for resisting the urge to take people up on their offer to toke up? (I'm never pressured into it, but it's like the dieter who's offered some chocolate cake — it's there, it looks sooo good, and the fact that other people are doing it makes it seem more "okay.") Thanks so much.

Recently, many of my friends have been doing methamphetamines. Often when they start to come down, want to come down, want to "level" out their high, etc. they take Xanax!!! Now I know Xanax is an anti-anxiety drug, and meth speeds your heart up. So can mixing the two ("reds" with "blues") be especially bad? I keep trying to tell them that it doesn't sound like a good idea...but they know that I hate pills so they DON'T listen. "They know better!" But I haven't been able to find any info specific to my question in other places. CAN YOU HELP?

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 two friends who were recently diagnosed with depression. They were both prescribed Prozac by their respective doctors. Both of them are heavy marijuana users and both failed to mention that to their doctors. One has been on Prozac for two months and the other for six weeks. I have noticed that their behavior has become strange: mood swings, paranoia, oversleeping, fatigue. They continue taking their Prozac (20 mg a day) and continue smoking pot. I am afraid that there might be some negative interaction between the substances, one being an antidepressant and the other a depressant. Can you provide some insight?

I have never had a problem with alcohol tolerances in the past. I could drink at least four or five drinks and be fine that night and the next morning. Now, I find myself getting violently sick after drinking just one or two. Even after a glass of wine I want to puke it up. Is there something physically wrong with me? I know the obvious solution is to stop drinking entirely. But, I shouldn't be this sick after drinking just one drink. Have you ever heard of this before? Can you help me figure out the problem?

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?

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.

I'm curious about drugs — in particular what happens when you chemically combine methamphetamine and PCP and how it might affect the body. Some places online say they're the same thing, but I'm not so sure.

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?

I was really drunk and don't remember the night clearly, but I think I may have had sex. Now I don't know if I could be pregnant or not. I had never had sex before this. Help me please!
