What are the effects of marijuana on libido and fertility? My boyfriend smokes like crazy, and although he has been smoking for a number of years, I am worried about him.

I have a question. I read what you wrote about how long marijuana stays in the system. I have smoked every day for the last three months, but have now stopped completely. I am assuming it will stay in my system for three months. I regret this now. I want to look for a job and many firms drug test. I see on the web that there are kits that can be used to help pass the test. Do they work?

Thanks for your advice. I've never smoked before this and never will again!!! Thanks!

I have two concerns:

My boyfriend claims psychedelics open your mind to new ideas/perspectives and help you experience the "spiritual world." I maintain that anything you see or think is just a result from a brain overloaded on chemicals. However, I am beginning to feel closed-minded, and I would like to have your opinion on psychedelics — are they beneficial if used for a one-time experience, and will they immediately/permanently alter the way I view the world and myself? Given that I have doubts, should I even try anything this mind-altering? I have read your answers pertaining to short-/long-term effects, but I wanted to know if there was any actual evidence of the beneficial effects.

Many of my friends take Adderall while they drink. What are the possible health risks of doing this? I know Adderall is a stimulant, so can you drink much more alcohol while on it without feeling the effects as much?

A friend of mine has an essential tremor disorder. She smokes weed almost everyday because she said it helps her to stop shaking. She tried all kind of medicines doctors have prescribed her, and botox and acupuncture. None of them helped her. Any advice?

I've heard that drinking coffee and grapefruit juice at around the same time can extend the effects of caffeine. Is this true? I know that grapefruits can increase the bioavailability of some drugs... what about caffeine? Is this at all dangerous?

Are the health risks of drinking Red Bull and vodka in moderation (two to three) drinks an evening any greater than drinking two or three rum and Cokes, or two or three anything and Mountain Dew?

(1) I have a daughter who just joined AA. She has a drinking problem. What are our responsibilities to her as a husband, father, mother?

(2) Should any alcohol be kept in her house or our house (we are the parents) when she is around?

(3) It has been said that alcoholism runs in families — is this true? Does it seem to skip generations? If so, why?

I know that it is extremely dangerous to mix viagra (or other ED drugs) and poppers (amyl nitrate), and that one should wait for 24 hours after using viagra (to let it get out of your system) before using poppers. My question is what is the waiting period after using poppers before it is safe to use viagra? In other words, how long before the physiological effects of poppers wear off?

Why is beta-carotene dangerous for smokers?

Do any alcohols have any specific benefits? As in, is tequila better than vodka? And is red wine the best choice because of its antioxidants?

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.

What is "gaming addiction"? Is it a real thing? I can play some games, like World of Warcraft or League of Legends, for a whole day, and I've sunk 150+ hours into RPGs. How many hours in front of a screen are too many?

What are strategies for drinking less in a social situation or for avoiding driving while impaired?

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?

Is it possible to die from a pot overdose?

I was wondering if the rumor that smoking cigarettes stunts your growth is true? I am a smoker (not proud) but I do believe it may have stunted my growth or at least slowed it down. And if it does, is it permanent? Like, if I stop smoking, will my growth continue to do what it was originally going to do? Any information is helpful. Thank you I love this site.

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'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?

If someone drinks milk before consuming alcohol, will it help you from getting drunk by "coating your stomach"? Why or why not?

I heard somewhere that smoking reduces your sperm count. Is this true? How else, other than being a carcinogen, is smoking harmful?

I'm a college student who is struggling with the decision on when to see a doctor for treatment with my depression symptoms. I believe that I need to get treated for depression, but I'm just as scared about not getting treatment as I am about starting antidepressant drugs in my current lifestyle. As far as I can tell, I'm exhibiting the classic symptoms of depression, and have been for a while — frequent crying fits, days where I lose all motivation, and sometimes, even thoughts of suicide. But I drink frequently, almost every weekend, and use marijuana occasionally, and I am quite unsettled by the possible interactions between antidepressants and these other substances. In my day to day life I do very well — I hold a good GPA, have good relationships and a good social life, function well most of the time, and stay in shape for sports. I don't intend to change my lifestyle significantly to make room for depression treatment. But when do I need to get help? I don't want to force an unnecessary change on myself, but I don't want to put myself in danger from depression, or even worse, from the drug interactions between antidepressants and alcohol or weed. What is the tipping point?
