Marijuana has been blamed for causing car accidents and fuelling acts of violence.
But now controversial new research suggests that couples who smoke the drug together are actually less likely to be violent towards one another.
And experts claim it's not just the effects of cannabis on the brain, but the fact that couples who use it may share similar values and social circles, that may reduce the likelihood of conflict.
Researchers at the University at Buffalo School of Public Health and Health Professions and Research Institute on Addictions, in New York, studied 634 couples to find that the more they smoked marijuana, the less likely they were to engage in domestic violence.
