Thousands or millions of folks do drugs of different sorts - opiates, alcohol, pot, LSD, cocaine, and so on, both legally and illegally - without doing those things. Just like someone can take prescriptions or drink alcohol safely, a person can do illegal drugs safely. Sitter for the kids, no driving, and so on.

Want to reduce driving under the influence? Have stiff penalties while making sure there is public transportation for all so that it can realistically be avoided.

Folks partake in domestic violence without substances. It should be punished and I don't think it matters if a substance was involved or not. Abuse is abuse and substances do not mean abuse. Sometimes, they are a bonding thing (MDMA especially).

Agression really depends. Teenagers can be quite aggressive. I can be quite aggressive depending on my hormones. A testosterone glitch can make folks aggressive. And so on. It really more depends on what the outcome of "aggression" is. Did you commit assault while aggressive? Charge for assault. Or whatever. If it just makes you an asshole, well. Don't be surprised if folks spend less time with you. Or maybe you instead feed that aggression into basketball or other sports so it doesn't matter at all.

The entire point is that drugs aren't necessarily dangerous beyond whatever physical dangers they do to the user. We can use the existing laws to punish things like assault.
