Governor Deval Patrick said he would likely vote no on Question Three this fall.
During a Thursday live chat with Patch, a reader asked Patrick how he would vote on the ballot question and whether the governor was for or against the legalization of cannabis.
"I am not too energized on this issue, personally. California's experience has been mixed. I will probably vote against it. I respect the opposing view, though, especially those whose concern is for people in constant pain," wrote the governor.
Proponents say medical marijuana will help ease the pain and suffering of cancer patients and other eligible residents. Opponents, meanwhile, say the law is a back door to full legalization, and that medical marijuana can be dangerous.
If approved, Question Three would "eliminate state criminal and civil penalties for the medical use of marijuana by qualifying patients." Qualified patients would be allowed to hold a 60-day supply of marijuana for personal use.
California has allowed medical marijuana use for years, although it remains a contentious issue in the state. The state law has not prevented federal authorities from raiding medical marijuana clinics and shops, and impounding the product found there.
