Well yes but this is a nitpick in my opinion. Drug possession in personal amounts is not a criminal offense. So they are no longer "super illegal" you could say. It's in the same category as a driving offense or something like that. Same in Czech Republic.
It's not a nitpick at all. Without legalization there is no tax money from sales of recreational drugs, and the black market still exists to collect that profit instead. Decriminalization also does not fix problems like contamination of drugs, mislabeling, or inconsistent dosage, whereas legalization would.
Decriminalization is better than nothing but actually misses out on most of the benefits.
