I typically don't smoke that much weed, especially during the school year. Last year, for instance, I smoked maybe once a month. This summer, though, my friends and I have all hit the bong pretty hard. I'm worried such frequency over a few months could impair my long-term capacity for learning. Is there any salt to this concern?

My partner suffers from mild social anxiety. Is it possible that this disorder can be aggravated by stimulants such as coffee? I have noticed that on days he drinks lots of coffee, the disorder seems worse, and he is more uncomfortable.

Please help! If we can eliminate possible aggravates of the disorder, he would be so much happier!

I have a history of "experimentation" (infrequent or occasional use of ecstasy, 'shrooms, and other drugs — mostly prescription pills). I am completely sober now, but am worried about long-term damage to my brain. I used drugs infrequently (no more than three to five times for each substance), but drank regularly. How worried should I be? Is there anything I can do to combat long-term effects?

I've recently dropped acid about 5 times a week for oh... about 3 months now. I have grown mentally and spiritually in ways unimaginable. But friends tell me I am in a false reality now; this brings me off my trip although I now only trip mentally (without the drug). In your opinion, has acid hurt me or helped bring my level of consciousness to a higher level? Am I reaching a state of Nirvana or am I simply a burn out? Please answer this question... I haven't the gall to ask anyone else.

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?

I just started taking Zoloft today. I am going on vacation next week and am wondering if it is safe to drink while on this medication. I can't seem to get a straight answer from anyone. I'm not talking about drinking to oblivion; I'm talking about having a couple of drinks by the campfire. Is this okay?

I, like many Americans, take Zoloft, 50mg a day.

My question is: Will this show up or alter in any way a pre-employment drug test for future jobs? Should I even mention that I am taking it to the screener?
