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?

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?

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?
