Back in the 30s, there was a melodramatic little propaganda film called Reefer Madness. In no uncertain terms, it thundered on about the evils of the demon weed – that mind-destroying drug marijuana. Naturally enough, hip youngsters thought it was hilarious. They still do. But, as it turns out, reefer madness is no laughing matter. It really does exist. Wait till you see the latest, the most comprehensive research. It proves cannabis really can cause psychosis, can wreck young brains. Not only that, the drug itself is stronger, super strong and the users are younger. Much younger – 10 and 11 years old.
