Legislation and regulation  

Industrial hemp production is regulated in Western Australia (WA) under the Industrial Hemp Act 2004 (the Act) and the Industrial Hemp Regulations 2004 (regulations). 

The Misuse of Drugs Act 1981 prohibits the cultivation, harvesting and/or processing of cannabis of any kind in Western Australia. The Industrial Hemp Act 2004 provides industrial hemp licence holders (who are carrying out activities which are authorised under an Industrial Hemp licence) a defence against prosecution under the Misuse of Drugs Act 1981.  

The Industrial Hemp Act 2004 states that industrial hemp, "...means cannabis, the leaves and flowering heads of which do not contain more than 1% of tetrahydrocannabinol" (THC). These low levels of THC mean that industrial hemp plants do not have the psychoactive effects associated with prohibited cannabis varieties (marijuana) nor medicinal varieties harvested for THC and CBDs.
