In a similar vein, the report found that since 2017, emergency department discharges with marijuana-related billing codes among children aged 0-9 years saw a significant, 66 percent increase.
Since the release of 2017 data, daily or near-daily use among Colorado adults has increased 20 percent (7.6 percent in 2017 versus 9.1 percent in 2019), and nearly half (48.2 percent) of adult marijuana users in the state consumed the substance on a daily basis. This is concerning as daily use of today’s higher potency marijuana has been shown to increase the risk of developing severe mental illness such as psychosis up to fivefold.
Adult use is especially problematic as seen in recent research from this week published in the Journal of American Medical Association finding negative neuropsychiatric symptoms in THC users over 50.
Since the implementation of the commercial market in 2014, the report found that marijuana use among Colorado adults has risen 40 percent.
In 2019, past-month marijuana use among high school students (20.6 percent) remained lower than past-month alcohol use but was significantly higher than past-month use of cigarettes (5.7 percent) and illicit prescription drugs (6.9 percent).
When it comes to one of the more concerning trends associated with marijuana legalization as it pertains to public safety, the CDPHE report found that marijuana-impaired driving has increased 40 percent since the implementation of commercialization in 2014. This report comes on the heels of a news report that marijuana-related DUI’s in Colorado have increased 48 percent in the last year.
Furthermore, the report found a significant, 24 percent increase in high school students admitting to driving a vehicle after recently consuming marijuana in the past month. In 2019, the rate of high schoolers driving a vehicle after consuming marijuana (11.2 percent) remained significantly higher than that of high schoolers driving after alcohol use (5.9 percent).
The report also found that around 4.9 percent of postpartum-currently breastfeeding mothers in Colorado were consuming marijuana. This is concerning as research has found THC to be present in a mother’s breastmilk up to six days after consuming marijuana.
