On Dec. 13, 2016, the Colorado Department of  Public Health and Environment announced $2.35 million in grants to researchers who can help the state better understand the impacts of marijuana.

Most of the grant money—$1.68 million—will go to two studies on marijuana use and driving, according to a Dec. 13, 2016, article in the Denver Post. One of those studies will compare drivers who smoke marijuana occasionally with those who smoke heavily. The other will look at how marijuana extracts, when smoked, affect driving and cognitive functions.

Grant money will also go to other studies, including those intending to find out how long marijuana remains in mothers’ breast milk; discover the risks of marijuana for people with heart problems; and measure the negative health impacts of pot edibles, the Denver Post reported.

Dr. Larry Wolk, executive direction of the Department of Public Health and Environment, said in a statement the research will be “invaluable” in Colorado and across the U.S.

“The findings will inform our public education efforts and give people additional information they need to make decisions about marijuana use,” Wolk said.
