CANNABIS 'NOT RISKY'

STUDIES had found it impossible to prove cannabis adversely affected
driving, an Adelaide University researcher said yesterday.

Professor Jack Maclean, director of the road accident research unit,
said there was no doubt alcohol affected driving adversely, but that
was not the case with marijuana.

``It has been impossible to prove marijuana affects driving
adversely,'' he told a conference in Sydney.

Marijuana might affect performance in a favourable way by reducing
risk-taking, he said.
