Professor Wayne Hall dislikes drugs. So much so, he advises the World Health Organization on drug issues and teaches “addiction policy” at the King’s College in London. According to Hall, he’s gone through 20 years of research and can show that marijuana leads to mental illness, sick babies and car crashes.
His findings are based on government-funded (anti-cannabis) reports from the last 20 years that he hand-selected. Basically, he’s parroting other, old reports and passing it off as something new.
