I get the sense that the author hasn’t tried many or any of these substances and is trotting out the standard line. I didn’t see alcohol, cigarettes and Oxycontin mentioned.

If we’re going to have an adult conversation about addictive substances we should first talk about sugar and junk food. We should also discuss the dangers of a sedentary lifestyle, lack of healthcare and community, ignorance of mental health, motor vehicles, pollution, the criminal justice system, Judeo-Christian culture and being a person of colour. Those will form the major risk factors for human health.
