1. Execute drug smugglers.
2. Imprison drug dealers.
3. Sentence drug users to internal exile.
Details on #3:
It doesn’t make sense to send drug users to prison. Instead send them to special communities to dry out. Each user gets a small bungalow, a food allowance, and a plot of land to plant a garden. And, of course, each community is surrounded by barbed wire.
I’d recommend land mines.
So you want to starve them to death?
“Sentence drug users to internal exile”
That’s another possibility.
Ref your three part plan, i notice no action against the banks who handle the cartel cash? Without support of the banks, the trade would be dealt a HUGE blow.
For example, HSBC literally started as a drug smuggling bank to support the opium trade the Brits raped China with.
