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.?

My question is this, How much do you know about what the asthma medication called Clenbuteral does to a normal healthy male in regards to body building? What are the adverse effects? And I don't need to be preached to about why I should take it or not. I just want the basic gist of what it does. Can you answer this? By the way this drug is not used in the US for any reason.
