So, supply has more than kept pace, THC content increased, and the price went down. All this put together tells you that marijuana use has increased? Uh-huh.
Past month use is up a little, but it's been flat since 2002.
There have been over 14,000,000 past month users for 3 straight years now, so you are correct. BUT-- those are the 3 highest recorded numbers since 1985. According to the NSDUH surveys, the last 3 years have seen the highest past month mj use since the office of Drug Czar was created in 1989!
