> I disagree. If you take [action], and it was a necessary and sufficient condition for [consequence],

That's exactly the thing though isn't it. Marijuana is (was) illegal, and has VERY LITTLE amount of violent crime related with its market. Making something illegal isn't enough to induce violence alone. So the [action] of (making drugs illegal) itself alone isn't enough to make [consequence] of (additional violence) to be a certainty.

Or, consider the simple case. I insult you, you punch me. You clearly wouldn't have punched me if I didn't insult you. Who's at fault here?

Actually, substantial cartel activity was associated with marijuana, with significant violence associated with production in Sinaloa and transport into the US. It was a huge fraction of cartel activity, both in volume and dollar value.

The main reason cartels didn't take over entirely was A) there are few effective barriers to production, B) the low density of the product favors domestic supply, and C) making high quality product is time consuming and logistically complicated.

And there is still violence associated with marijuana in CA because about 80% of the market is still underground due to the extreme difficulty of navigating the current regulations.

There is plenty of reading material on this.
