Deport the drug cartels, stop the border tunnels and much of the "too available" heroin problem will be solved. One can start out with a $3 high starting that dark tunnel to a hundreds $$$ a day habit or death by overdose. It only takes 3 days of use to become addicted. The drug cartels are operating in all cities - if the DEA has a map of known cartels operating, GET RID OF THEM - they are criminal illegals.
