So this slide is gonna shock you the substances are prohibited today were legally marketed in the past. Heroin which marketed by beya; Cocaine toothache drops to children to prevent or to protect them against toothache; Camels cigarette were marketed something doctors smoke more and therefore somehow more healthy. I am hopeful the 20 years from now people will be just the shocked to see adds of packet chips, aviated drinks, sugar stereo, French fries from fast food restaurants and chicken nugget from fast-food restaurants and processed food like this, is just a toxic and addictive.
