There are also some incorrect definitions being peddled by law enforcement like higher chance of addiction, however hard drugs like LSD clearly contradict that.
As far as this article goes, I read it and I'm not sure what part of the hard drug meaning was meant to be communicated here.
If the author had written "Monads are a flavour of Pringles" (once you pop, you can't stop), it would have been marginally less bad an analogy.
As a pharmacologist, the phrase is meaningless to me. There is literally no distinction between 'hard' or 'soft' drugs
The terms are meaningless to me, I have no reasonable way of classifying anything into those categories because the categories literally have no meaning
Glad I'm not a pharmacologist, so I can understand the term in this context.
The terms and how they are used have zero correlation with reality
"an addicting drug capable of producing severe physical or psychological dependence, as heroin."
But you already knew what was intended.
Caffeine is a hard drug, it also produces physical and psychological withdrawal symptoms
Nicotine is a hard drug, it produces physical and psychological withdrawal symptoms
Apparently the term includes all psychoactive drugs, which makes the term meaningless
Searching for 'hard drug' on the National Institute on Drug Abuse yields no results that contain any information on 'hard' or 'soft' drugs. Don't you think the national agency would have a definition if it were a real concept?

Searching for 'soft drug' just yields no results at all

Here is an article by a psych professor who works in the field of addiction:

If your technical definitions don't include this taxonomy, so what? It's a meaningful term among laypeople because it communicates exactly this taxonomy in a single word.
It doesn't matter if some people can agree on something when that concept is objectively and demonstrably not only false but systemically harmful
PS alcohol is more harmful than heroin physiologically. Alcohol would be one of the 'hardest' if we were going by physiological and societal risk
Editing to add: we can't not include alcohol and nicotine in the general category of drugs. They are undeniably drugs and anyone who tells you otherwise is a victim of the previously mentioned misinformation
