Free will? About what? I could take my guns to some church today, or a store and open fire. I wouldn't choose to do so. So, is that choice actually available? I could choose to have homosexual sex even though I am heterosexual. I dont want to. Not what I would choose. So, is that choice available to me? Same with stimulants or opiates. Not my bag. I wouldn't choose that.
So if you have free will, go get loaded on hard drugs and offer sex to some ugly strangers. Otherwise your free will means nothing and you enslaved by your programming. People are Meat machines with no autonomy. Bacterium. Ants. Monkeys. Sorry about it.
