"Wider availability of medical marijuana in Colorado starting in 2009 coincided with an increase in calls to poison control centers and hospital discharges, according to a study published in the American Journal of Preventive Medicine.
Researchers led by Jonathan M. Davis, PhD, from the University of Denver, found that the public health effects were significant — a 57% increase (95% CI, 43.4 - 72.0%, P < .001) in marijuana-coded hospital discharges from 2007 to 2013, and a 56% increase (95% CI, 49.0 - 62.8%, P < .001) in calls to poison control centers after 2009.
“Many doctors see the whole medical marijuana movement as a scam. They don't see enough evidence to support it. On the other hand, we only have two cannabinoids — and there are over 80 cannabinoids in marijuana smoke,” Dr Hill pointed out.
According to the National Cancer Institute, several controlled trials support the use of cannabinoids for nausea and vomiting, but there is insufficient evidence to support the use of cannabis. In a recent randomized controlled study (N=30), dronabinol provided a longer analgesic effect than smoked marijuana, with lower abuse-related subjective effects."

Note the closing recommendation for more studies, given the full impact of legalising marijuana is still unknown. Surely we don't want to create more and bigger problems than we are hopefully removing?
