According to a study published in the journal Psychology of Addictive Behaviors, couples who use cannabis are less likely to have violent relationships compared to non-users.
The study followed over 600 couples for a span of 9 years and measured their behaviors over that time.
Just the opposite effect was the case if only one partner uses marijuana but not the other. The study suggests that the blissful results largely come from the fact that marijuana provided couples with a shared interest that also reduced anxiety.
