Lately, my boyfriend has been sleepwalking. I'll wake up, and he will be sleeping elsewhere — downstairs on the couch, his roommate's room, etc. At first, we thought it was funny. However, now that it has reoccurred (more than once or twice), he is very upset about it. He thinks it is from drinking too much. Could this be the case?

I'm thinking about trying heroin. However, this prospect makes me nervous because of all the media reports of people becoming so quickly addicted to it, wasting away, and even dying from overdoses. Any advice?

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.

I have heard that people can become trapped in their own world of hallucinations permanently from taking 'shrooms, acid, or other hallucinogens and have to live in a mental health facility because they are so out of touch with reality. I'm wondering is this true? And if so what is this medical condition called? I've heard of Hppd, but what I have read about it, it doesn't sound exactly the same. I'm also curious what the likelihood of this happening would be and if it is dependent on the use of many drugs, dosage, or the user's mental state or other preexisting health conditions that could affect this. I'm really hoping you can answer this question because I haven't found any reliable sources about this topic.

Thanks so much!

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?

I want to know what it is when you spontaneously trip without dropping tabs or anything. I've never had any drugs except marijuana. It is weird. I know that tripping is an induced psychosis, so am I psychotic or what? I was seeing a shrink and will be going back into treatment next semester. I think substance use is boring and a complete copout on life. I've made a lot of discoveries without needing to trip. Why does this happen? Tell me what you know.

Does acid (LSD) have a detrimental affect on women who use the birth control pill? Is it possible for a woman to be impregnated by pre-ejaculatory fluids four days after the menstrual cycle after unprotected sex?
