Cannabis and Driving in Australia: Laws and Penalties Explained

In Australia, it is illegal to drive while under the influence of cannabis. The presence of any detectable level of THC, the active ingredient in cannabis, in a driver’s saliva is considered a criminal offense. The legal limit for THC in saliva is 2 nanograms per milliliter for most drivers, although for novice drivers, commercial drivers, and drivers of certain heavy vehicles, a zero-tolerance policy applies.

Penalties for driving under the influence of cannabis in Australia can be severe. For first-time offenders, the penalty may include a fine, a period of license disqualification, and potentially even a prison sentence in some cases. Repeat offenders can face more severe penalties, including longer license disqualification periods and longer prison sentences.

In addition to criminal penalties, driving under the influence of cannabis can also have serious safety consequences. Cannabis use can impair a driver’s reaction time, coordination, and judgment, and increase the risk of accidents and fatalities on the road. As such, it’s important for all drivers to avoid using cannabis before driving and to be aware of the legal and safety risks associated with cannabis and driving.
