I watched this very interesting documentary on the herbal Kratom - some parallels with cannabis and govt inducing 'reefer madness' hysteria - apparently has been folks with opioid addiction and veterans with PTSD - and now forces are trying to make it illegal - follow the money. Wondering if any ME patients have tried Kratom and what your experience was? https://en.wikipedia.org/wiki/Mitragynine A Leaf of Faith | Netflix
I'd be careful taking Katrom. It is dependence forming and many people online have talked about having difficult times stopping it. That's kept me from trying it.
Not relevant to the OP - but Kratom is illegal in the UK. The sale, import and export of it have been banned since 2016.
