The entire world heard him say that he believes the opioid crisis was caused by marijuana. And that good people don't use marijuana.
Maybe that why the entire world is doing what they know is best for their own country, several countries have already legalized medical MJ. Several more by the end of this year.
USA accounts for 5% of world population and consumes 95% of the opioids produced. How could the DEA not see that trend????
