Alcohol and weed are not good examples because these are failed interventions if you consider them harmful. Consumption of both exploded in the last few decades.
This is why I use smoking: it's also legal or semi-legal, it used to be prevalent but its popularity cratered.
"Consumption of both exploded in the last few decades." -> I don't know about weed, but it's definitely not true for alcohol, it's roughly stable; in USA there has been some decrease in per capita consumption since a peak in 1980s - see https://www.who.int/substance_abuse/publications/global_alco... for example.
