Legalizing dangerous drugs

Dangerous drugs, I define as those likely to cause brain lesions of sorts; the top three: nicotine, meth, heroin; then cocaine, weed.

Under a legal environment, the vast bulk of society that rejects their use will want dangerous addicts with brain lesions isolated. The liability for keeping that so will be the legal drug dealer, a sort of drug courier that carries responsibility for isolating his distribution from society. So the new system becomes based on tort, the drug dealer highly motivated that his clients are tucked away in nice safe houses when they use. The great bulk of the net after sales will be devoted to legal bonding, a huge expense on the dealer.

Should drug dealers be allowed to mass market? No, tobacco dealers are denied the privilege. Society will ban mass marketing of suicide tools, one way of another. I don't think stacks of cigarette inventory should be visible in liquor stores.
