The legalization of medical marijuana is a good way to fight against overdoses to painkillers.
In thirteen American states that have legalized medical marijuana, the number of patients who die from overdoses of painkillers is 25% lower than in states where you can not get cannabis legally, according to a study published in the journal JAMA Internal Medicine.
In their paper, researchers at the University of Pennsylvania did not examine the causes of this decline, but other previous studies provide interesting clues.
In 2011, a professor at the University of California San Francisco had found that the psychoactive ingredient of cannabis enhance the effects of opiate painkiller. After a certain amount of opiates, patients studied had inhaled cannabis in a spray bottle for several days without taking medications, and all had reported a decrease in pain. “This preliminary study suggests that some patients may be more moderate doses of opioids if they use cannabis at the same time,” concluded Professor Donald Abrams.
“I think it would be interesting to do a larger study comparing high THC versus high CBD cannabis strains in association with opiates in patients with chronic pain and perhaps even having a placebo as a control,” Abrams said. “That would be the next step.”
It is currently possible to be prescribed cannabis legally in 23 American states and the majority of therapeutic uses of cannabis are associated with chronic pain.
