Vicodin
4
Helps with pain, and even if you don't have pain it makes you feel good. It gives a sense of optimism and joy, as well as relaxation. Of course these are very addictive, I wouldn't recommend taking them for more than a few days straight at a time unless you are prescribed them for pain. I'd give them a 4/5. Not a 5/5 only because of how easy it is to become addicted.
