'Grown men, screaming in pain, sweating profusely, vomiting every 30 seconds and demanding to be allowed to use the shower'

There is mounting evidence to support the existence of a new syndrome afflicting heavy cannabis users, after the world's first cases were found in South Australia.

The condition "cannabinoid hyperemesis" was first identified in a group of about 20 heavy drug users in the Adelaide hills in 2004, and a new case has emerged this time in the US.

The syndrome is characterised by nausea, stomach pain and bouts of vomiting - ill effects which, oddly, sufferers say they get some relief from by having a hot shower or bath.
