The biggest problem here is that at least some of your politicians are taking an easy line on the drug epidemic by blaming it on outsiders 'drugs coming in through the borders - arrrrgh!' . That's much easier than saying 'what is our society doing wrong when so many people feel the need to dope up - what can we do to fix things here?'

Making it harder to smuggle drugs won't stop people from smuggling drugs, it will just increase the price of drugs.

Getting a lot of people to stop taking drugs will not only fix their problem it will fix the smuggling problem.
