There is a pretty good evidence that making a drug illegal may reduce usage rates, but it does this at the costs of increasing the amount that is used in a sitting. This increase in binging leads to a higher rate of addiction and ODs. So while you might argue that the number of people using can decrease, this is often paired with an increase in the overall harm that drug abuse has on society (even before you account for the harm caused by treating drug abuse with jail time.)
