Overdose deaths involving synthetic opioids other than methadone, which includes fentanyl, increased almost 47% from 2016 to 2017. Roughly 28,400 people died from overdoses involving synthetic opioids other than methadone in 2017.
Kratom was on the DEA’s list of drugs and chemicals of concern for several years. On August 31, 2016, the DEA published a notice that it was planning to place kratom in Schedule I, the most restrictive classification of the Controlled Substances Act.
Like other drugs with opioid-like effects, kratom might cause dependence, which means users will feel physical withdrawal symptoms when they stop taking the drug.
