We've used Cannabis for how long in the US??

It feels like cannabis is all the rage right now, but in reality cannabis has been used by humans for thousands of years.  It gets ugly in the U.S. in the 1930s.

Cannabis sold in pharmacies & doctor’s offices to treat variety of ailments by companies like Lilly and Parke Davis.
