The first possible choice for my final paper is about drug legalization. I don't mean the usual legalizing weed, but the legalization of hard drugs. For example, there are countries in which heroine is legal. These countries have clinics where they provide clean needles and a safe environment, and even medical attention if something bad happens... The two stances are if they should be totally illegal or if there is a point at which we should stop punishing addicts and help them get their fix safely.

The other idea are the different treatments for mental disorders for OCD in particular. There are different methods such as cognitive behavioral therapy, behavioral therapy, and medications. I would go into detail about all of these options and tell which one is the best, although it seems that a mix of 2 or all 3 of these options may be best there is a lot of research to be made.
