Cannabis is not a cause of anti-social behaviour.
And why do those who are morally (or politically) concerned 'about drug harms' resist change (ie: "we don't need a third drug!") when cannabis is so prevalent and so benign by any comparison yet 'in their name and mine' its draconian sanction so damaging.
"The Advisory Council also found that cannabis use isn't actually associated with antisocial or criminal behaviour, but the public perception is that it is, because there's a lot of misleading information which confuses people." - Dr Margaret Melrose, reader in applied social science at the University of Bedfordshire
Why do we make rational movement in the policy analytic standard seemingly 'illegal to discuss' if not downright impossible?
