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?

My girlfriend tells me she uses marijuana to calm herself if she is having a stressful day. She has been doing this for many years. She says smoking pot is like self-medicating — it is better than using anti-depressants. She also claims smoking pot helps with depression because of how it helps produce serotonin in the body. What is serotonin and how does it help depression? Does smoking pot really help with managing your anxiety, depression, etc.?

Is it ok to drink alcohol while taking Xanax?

I really want to try pot because I am SICK of being uptight and careful all the time. I have been depressed and anxious for several years and I just want to feel SOMETHING different. But I've had a couple of panic attacks (both related to medication) and they were the most frightening things I've ever experienced. I'm scared that pot would do the same thing to me. What do you think? I know you can't encourage me to smoke pot but I would very much appreciate an honest answer, which I know you always give. (I know that smoking pot is not the best thing to do when you have depression and anxiety, but it would only be once, and I would be with friends. By the way, I'm not currently on medication as I find it useless. But I'm not trying to self-medicate. I just want to remember what it's like to experience an emotion that is not depression or anxiety). Thank you very much.

Is it possible to die from a pot overdose?

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?

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'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?
