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.?


Can excessive orgasming deplete endorphins?

Since orgasms cause a release of endorphins into one's cerebral-spinal fluid and endorphins are also somewhat responsible for the emotion of happiness, etc., is it possible that excessive masturbation and/or intercourse would lead to a depleted level of endorphins in the system that could in turn cause one's affect to become somewhat "flat"? Could a sustained low level of endorphins in the system induce depression and/or mood disorder?


Does altitude have any impact on sex?

I'm sending you this message from the top of the Sierra Nevada mountains of California. My wife just experienced her best orgasm ever. We live by the beach, a very low altitude... so that made me wonder, although crazy, "Does altitude have any impact on sex?"

If it doesn't impact sex, it definately impacts the lube bottle as it came squirting out on it's own...
