ok seriously these campaigns are based on sheer ignorance. Both the "effects" of cannabis of which this person describes, are the combined effects of that of cigarettes and alcohal. Half of these may not be true but even if they were, alcohal is clearly more dangerous and life threatening than weed. And the amount of smoke that cigarette smokers inhale in a day is so much great than that of the recreational cannabis smoker. If anything were to be banned it should be cigarettes and alcohal before weed... (not implying anything should be banned, but jesh just relax on the cannabis)
