The Australian Medical Association has called on the state government to outlaw synthetic cannabis before people harm themselves.

Synthetic cannabis such as Kronic, have been thrown into the spotlight in recent months after it emerged that employees in already dangerous work environments, such as miners, were not able to be stopped from smoking the drug.

At the moment smoking Kronic is still legal.

Perth-based ChemCentre has begun testing the drug among urine samples of mine workers, and said earlier this week they were receiving hundreds of samples to test every day.

AMA WA president Dave Mountain said the powerful synthetic drugs should not be freely available within the community, and said the state government needed to ensure it was banned immediately.
