CANNABIS, THE 20 YEAR STUDY
A paper by Professor Hall, advisor to the World Health Organisation, builds a compelling case against those that deny the devastation cannabis wreaks on the brain.
Professor Hall found one in six teenagers who regularly smoke the drug, become dependent on it. Cannabis is highly addictive and opens the door to hard drugs. Those who try to stop taking cannabis often suffer anxiety, insomnia appetite disturbance and depression. Even after six months less than half can stay off the drug for six months.
Professor Halls main findings are that regular use leads to long-term mental health problems and addiction.
There is no doubt that heavy users experience a withdrawal syndrome as with alcohol and heroine.
