Utah State University researchers have grown cannabis plants since 2018, when hemp cultivation was legalized.

A new analysis of cannabis research funding in the United States, Canada, and the United Kingdom has found that $1.56 billion was directed to the topic between 2000 and 2018—with about half of the money spent on understanding the potential harms of the recreational drug. Just over $1 billion came from the biggest funder, the U.S. National Institute on Drug Abuse (NIDA), which doled out far more money to research cannabis misuse and its negative effects than on using cannabis and cannabis-derived chemicals as a therapeutic drug.
