According to the Globe and Mail Veteran's Affairs Canada has statistics that show opiate requests are down as cannabis requests have climbed.
It is interesting that opiate prescription requests are down while rising rates of cannabis are being seen in Canadian veterans. The numbers show a decrease of 30 percent for bezodiazepines between 2012 and 2016. Opiates decreased 17% during the same period. Prescription cannabis has gone from 100 to over 1,700.
The data set is too small to establish cause and effect, but the trend may be one way to reduce the growing opiate problems in NH and the United States.
