I disagree.

It takes more than a single use of coke, heroin, or meth for a physical addiction to set in.

Plenty of people who try drugs are not addicts.

Drugs do not rewrite brains. People have willpower. People quit nicotine, people quit heroin, it is up to the individual.

People should be allowed to do what they want to their bodies. If they want to put heroin in their bodies, so be it.

I'm for personal responsibility and I'm against the government regulating what a person can do to his own body.

Governments should protect you against harm from others and fraud. Governments should not protect you from harm to yourself from yourself.

This is a survery from the Department of Philosophy at Indiana University-Purdue University Indianapolis. Philosophy was number with math/physics being number 1 for law schools. I suppose my facts were slightly off, but most people I know who major in philosophy are planning on going to law school. Neverthelesss, I have met people like your college roommate, but I feel those people exist in every major.

Do you realize that most Philosophy undergrads are pursuing law school? It is the number one degree of lawyers, because philosophy undergrads score the highest on the LSAT... What about people who major in subjects like English because they want to teach high school? The last time I checked, teaching high school required a degree.
