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.?


Is there a connection between emotions and physical pain?

When I hear someone make a negative comment about me it sometimes sticks and for some reason my chest will begin to hurt. A friend of mine said it was emotional shock. For a while the feeling went away, but then it got worse. Now the pain will range from my heart to my left arm, depending on how badly (depressed) I feel. In general, I want to know if I should be concerned or if it's just as my friend says: "emotional shock," that's just gotten worse.


What should I do if I'm successful but not happy?

I'm not in college anymore, but students could benefit from this question, too. I'm single with a 'great' job (pays well, insurance, pension, etc.), a decent place to live, no debt... in short, life could be much worse. But the only thing lately that makes me happy is doing kind things anonymously for people. I'm rather wealthy but don't want a big TV or a fancy car. I'd rather spend a vacation at a local monastery meditating and performing service. I'd be committing economic suicide to quit my job, and so many are worse off, but 'success through hard work' doesn't make me happy. I'm sure a number of students must have these feelings already. What are your feelings about this, Alice?


What are the common reasons for condom failure?

I live in Prague, Czech Republic — Europe. Before asking any question, I should tell you that I really appreciate your service. As for my question, I would like to ask you about the most common reasons for condom failure as a contraceptive method. I suppose that the most frequent one is condom breakage. But what are the others? I am especially concerned about pregnancy risk implied by the accidental transfer of sperm in pre-cum to condom by fingers while putting it on.
