Daily cannabis use is linked to ‘significantly lower odds of daily illicit opioid use’ among people with chronic pain, according to a new study
The study was conducted by teams from the British Columbia Centre on Substance Use (BCCSU) and the University of British Columbia (UBC).
The researchers looked at a group of 1,152 people in Vancouver who reported substance use and suffered from major or chronic pain.
The team found that daily cannabis users were half as likely to use illegal opioids including heroin to treat their pain.
The cannabis users also reported that the drug improved sleep quality and reduced stress and nausea, as well as symptoms of HIV and side effects of HIV antiretroviral therapy.
The findings suggest that cannabis could be used in place of opioids for pain management.
Senior author Dr M-J Milloy, a research scientist at BCCSU, said:
“There is preliminary evidence that states with legal cannabis access have lower overdose deaths and our study fills in some of the gaps of why that might be.
“This is more evidence that, for some people they can reduce their use of illicit opioid intake and reduce risk of overdose.
“Our scientists just have to figure out if there is a cause and effect and how to optimize it.’”
There were 1,495 opioid-linked deaths in British Columbia in 2017 and in 3,996 deaths in Canada as a whole. This was the second-worst year on record.
Opioids were involved in 47,600 deaths in the US the same year – 67.8% of all drug overdose deaths.
British experts fear that the UK could soon face an opioid addiction crisis of its own.
Doctors issued 40.5 million opioid prescriptions in 2018 alone, according to a review by Public Health England.
