> A further factor was cannabis. Attempts to quit left him feeling stranded in a “horribly profane” world, with a “tremendous narrowing of consciousness.” Substances that once served exploration soon functioned as psychological maintenance. “He just needed to be high on cannabis,” Harrison said. “That was his medicine… what drove everything,” keeping him from “bouncing off the ceiling.”

Clearly there were a number of factors contributing to his difficulties, but this sounds like it may be an underestimated one, maybe more than the mushrooms even. Cannabis dependency really can sneak up on people, and for some it’s quite difficult to get off it, with real physical and emotional symptoms.

Throughout my university years, many of my peers smoked cannabis on a daily basis, often several times a day. Most of them seemed oblivious to the fact that they might have developed a dependence; whenever anyone tried to talk to them about it, they dismissed it, claiming cannabis is completely benign and nothing to worry about. Today, I personally know that at least a couple of them developed serious mental and physical problems, and to this day, they are unable to cope with life without being high.

There should be more awareness about safe cannabis use and its risks rather than framing it as a "healthier" alternative to other drugs, with people usually saying "at least I am not doing X, I am just smoking weed".
