How benign is it?

Marijuana has undergone a makeover in recent years. Once viewed as the purview of hippies, deadbeats and jazz musicians, it’s gone mainstream. It’s no longer shocking for characters in movies or even TV to smoke a joint, and with voters approving marijuana for recreational use in the US states of Oregon, Alaska, Colorado and Washington, there’s a real sense of momentum. A recent Pew study showed that for the first time a majority of Americans support legalisation. No doubt these are heady, or should we say, high times for the cannabis plant. But while it may be increasingly accepted - and increasingly potent -  is it safe? A debate has been raging between pro and anti-legalisation groups over just how benign pot is.
