Drugs and Behavioral Sciences
The areas I have extensive knowledge of are drugs and their effect on the mind, body, and life of the person taking them.
Especially opiate drugs, but I do know some things about stimulants.
I'm not too well versed in benzos though (IE: Valium, Ativan, Xanax, etc) but I know a little bit.
I know a lot about psychoactive pharmaceuticals as well, such as Prozac, Celexa, Seroquil, Welbutrin, Geodon, Zyprexa, and some others. Plus I have a little bit of knowledge when it comes to other drugs.
Also I'm really knowledgeable when it comes to mental disorders such as severe depression, dysthymia, schizophrenia, post traumatic stress disorder, and general social phobias.
While I'm not a doctor I have lived in a situation where I was privy to an on staff psychiatrist 24/7 who specialized in drug treatment for more than six months.
Plus not to mention that I've been in therapy and taking various medications since I've been eight years old.
Also I just read a lot about these subjects because they fascinate me from an analytical standpoint.
What I can also give you is first hand experience and relay what I've heard from other people in similar situations and such.
