Talking about hunting and killing traffickers, this sounds tough, but it's mostly kind of if you want to shut down one cartel lab, maybe there might be someone else that might still fill the gap, as long as there is demand for these same drugs. The root causes are mostly loneliness, poverty, and lack of opportunity.
If government can spend so much energy in supporting childhood, proper treatment, and job programs, then we might see some real change. When the government prioritizes these things, education and social safety, then we can save.
There will always be someone to step in to fill the gap, when there are profits to be made. End demand, profits evaporate accordingly.
