Libertarianism espouses the core value of self-ownership and bodily autonomy. As such, libertarians reject any law or effort of the government to pass legislation regulating what a person can or cannot put into their own body.
While many libertarians generally do not condone the use of heroin or other hard drugs, they steadfastly support an individual's natural right to choose what they will consume--so long as they do not infringe upon the rights of others.
Libertarians believe that the government should have no authority to control what people consume and that federal drug scheduling is tyranny.
Libertarians believe addiction and drug abuse are private medical matters that should be dealt with between an individual and their doctors, therapists or specialists.
Libertarians argue for the decriminalization of heroin and other hard drugs, not necessarily as a way of condoning its use, but to dismantle the state's power to govern morality and punish personal choice.
Libertarians, and the official Libertarian Party oppose the U.S. War on Drugs.
