More to the point—a typical dose of kratom is less than $1; it’s hard to abuse since taking too much will just make you dizzy/nauseated/anxious, a mistake most users only make once; it doesn’t cause respiratory depression (doesn’t recruit β-arrestin2) so it (EDIT: probably, although we don’t know for certain) won’t kill you if you overdose; and if you’re in withdrawal, it will take you from “not fine” to “fine” within an hour without getting you particularly high or keeping you dependent like methadone/suboxone.
There are certainly downsides—e.g., it’s moderately addictive itself and can interfere with testosterone like any opioid—but its potential utility in fighting the opioid addiction epidemic is clear. If I had my way, it’d be guaranteed to remain legal and available over the counter to people over 18, thoroughly studied for side effects and drug interactions, and recommended/prescribed as an alternative PRN treatment for withdrawal symptoms—and other conditions like anxiety, if you don’t want to get hooked on benzos.
I know this: it saved multiple people in my life from opioid abuse, and myself from alcohol. That’s got to be worth something.
