Is marijuana a harmless way to relax or a dangerous gateway drug? The science says “No” and “We don’t know,” respectively. Arguments for and against legalization often misrepresent the medical effects of cannabis, some experts say. Several bills proposed in the 2017 session of the General Assembly would make recreational use of marijuana legal in Connecticut. Medical marijuana use for conditions ranging from post-traumatic stress disorder to cancer has been legal in the state since 2012, though dispensaries did not open until 2014.
