Are those really good comparison countries though? To me, it seems like some of their basic views on rights are antithetical to those in the US, going way beyond how to deal with drug problems.
Japan,Taiwan and south Korea as more examples. Japan has life sentences for opioid distribution/sale. Taiwan has mandatory 3 year sentencing simple possession of class 1 drugs (Opioids). South Korea also has very strict sentencing laws for opioid possession and usage ranging from 1 to 3 years. Most of laws were influenced by the Opium wars 100 years ago.
