Coffee - addicting, but mostly harmless unless used in excess.
Not exercising - bad, but not awful
Stress - horrible, but it's something we live with regardless
Prescription painkillers - seriously? Maybe this should be at the bottom, but it's not really that bad I guess.
McDonalds - O_o
Cigarettes - o_O
Depression - -_-
Alcohol - really bad, like the worst...but I still like it. >.> It's just an extremely dangerous drug that shouldn't exist.
Adderall - let me just say this...its use should be punishable by death and its creators should be castrated and hung by their entrails. Anything related to "fixing" "ADD" is just stupid. First of all, it's not "ADD", it's called being allergic to stupid shit like sitting in a classroom all day.
