Yeah, the United States government pretty much owns your body.
They tell you what you can and can't do with it. They say it's mandatory to wear your seatbelt in the car, but shouldn't it be your choice? By choosing not to wear your seatbelt, you're not hurting anyone else. The only person you're endangering is yourself. Same goes for drugs. If you want to put chemicals in your body, that should be up to you. As long as you aren't endangering the safety of others around you, what you do to your body should be your decision.
Eh, I don't really know what to write about right now. I apologize.
