The drug death figures today are horrifying, but unsurprising.
There cannot be a “free” market in general, but not in drugs, or prostitution, or pornography, or unrestricted alcohol, or unrestricted gambling.
That is an important part of why there must not be a “free” market in general, which is a political choice, not a mere law of nature.
Enacting and enforcing laws against drugs, prostitution and pornography, and regulating alcohol, tobacco and gambling, are clear examples of State intervention in, and regulation of, the economy.
We need a single class of illegal drug, with a crackdown on the possession of drugs, including a mandatory sentence of three months for a second offence, six months for a third offence, one year for a fourth offence, and so on.
