Legal marijuana sparking rise in bizarre 'cannabis vomiting syndrome' | Daily Mail Online
'Legal marijuana has given rise to a bizarre syndrome that makes heavy cannabis users violently ill, US doctors warn. '
'They reviewed admission data to hospitals and found an acute rise in the condition since marijuana became legalized and widely available for medical use. '
'Recognition of the condition is increasing and doctors are now recognizing the condition in patients regularly visiting hospital with severe nausea. '
'Marijuana is the most commonly used illicit substance in the United States, the authors note, with 18.9 million users in 2012. '
'The findings that cannabis can cause severe nausea runs counter to a widespread view that the drug has a powerful anti-nausea effect. '
