[_Schizotypy]

Can you explain what pharmacological properties of a substance makes a drug "hard"? This is defined nowhere in literature.

Disabling withdrawal symptoms, mainly. The literature has plenty of quantizations of harmfulness of drugs.

[_Schizotypy]

Cocaine has negligible withdrawal symptoms especially when compared to benzodiazepines or alcohol, so this is absolutely not the case. The literature that I have read does not say that any compounds are "hard" or "soft" The literature that I have read also has noted that the impact of alcohol and tobacco are worse than the drugs people always refer to as "hard" drugs.

cocaine and meth don’t have withdrawels. alcohol, benzos, and opiates do.

I’m not sure you could agree that one group is “harder” than the other.
