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!

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?

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?

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?
