US search interest for weed rose about 75% from 2004 to 2016, according to Google Trends.

This is just one more sign of a sea change in popular opinion about weed. Just recently, a Lancet study of US adults from 2002 to 2014 found an increase in usage from 10.4% to 13.3% and an increase in people perceiving no risk in occasionally smoking from 6% to 16%. And of course, legalization is gradually spreading across the country.

The chart below shows searches for the topic of cannabis, which Google gathers using deep learning.
