Are you one of the 10 million people who have used drugs like cannabis or cocaine ? Make no mistake, drugs are fun. They must be, given the scale of drug use and the long history we humans have of using them. Despite the upside of using drugs, it’s not an aspect that’s given the attention it deserves, a bit like the way no one seems interested in good news stories. Instead, when drugs are featured in the media it’s usually to panic about the latest incarnation of some new pill or powder.
