I have not seen anyone who died of this new drug Kratom. I haven't heard of it either. I do hear of and see deaths from legal opioid doses every day of the year.
Before stopping the import of this product and making it illegal, I would suggest to the feds to be sure this Kratom is not doing more good than harm to people. If it causes no significant respiratory depression and is not dangerous, the greatest damage it does will be to manufacturers and distributors of oxycodone, hydrocodone, buprenorphine, dilaudid, methadone, and the other legal opioids. It also might cut into the illegal diacetyl morphine (Heroin, a Bayer trademark) trade. From what I do know, Kratom leaves are no more dangerous than the old colchicine.
