Have you considered the benefit of a wall to help the fight against heroin and opium?
I've considered it and rejected it. Drugs will get in and can be manufactured here, wall or no wall.
What will help fight heroin and opium happened last week. They AMA is FINALLY providing stricter guidelines for the Rx of opioids for chronic pain. You do not need heroin to get over a migraine. The risk is wayyyyy too high.
