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?

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?

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'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.

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