Does marijuana produce serotonin?

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.?


Why have I started fantasizing about women when I've only ever liked men?

I have always been attracted to men, and have only been with men. I am currently happily engaged to a man, and have no doubts about our relationship. However, I've discovered over the past couple of years (even when I was with my previous boyfriend) that I do not like porn with men in it. I like lesbian porn! And anytime I've masturbated I've fantasized about women (never one that I know or have seen.) It's made me very uncomfortable, finally admitting it to myself. I do remember when I was in 7th grade there was a new girl at our school. When she got a boyfriend I was very jealous; I just assumed it was because she was new and I didn't have all her attention *ha* Is this normal? Am I out of my mind!?


Are other drinks besides water still hydrating?

I frequently hear that beverages with caffeine or alcohol are not good for replenishing fluids and preventing dehydration. But in reality aren't they just a bit less effective at hydrating your body than other beverages? In other words, if you were stuck in the desert with nothing to drink but beer, coffee and cola, would you actually be worse off and die of thirst sooner if you drank these beverages versus not drinking anything at all?


How long should I wait to use Viagra after using poppers?

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?
