If you wanna get rid of the bullshit opioid crisis, stop subsidizing it. The government should immediately cut off all medical payments for opioid treatment. If a hospital treats an opioid patient, they or the patient are stuck with the bill. Economics 101: When you subsidize something you get more of it.
Best way to get rid of it is to build a wall, police the borders, arrest and execute all gang members who are in our cities and towns. This problem would be over immediately.
