A proposal to use cannabis to battle opioid addiction is being processed in Maine.
Advocates point to a study in the Journal of Pain this year that found chronic pain sufferers reduced opioid use when taking medical cannabis. But the research falls short of concluding cannabis helps wean people off heroin and prescription opioids.
Maine legalised cannabis for medical use in 1999. A separate proposal on the November ballot would legalise cannabis for recreational use in Maine.
