If a person in NSW mixes drugs and driving, the door is open to a plethora of criminal offences, such as:
Whether a person is convicted of an offence depends on the circumstances of the case and if any defences are applicable.
First, let’s dive into the research.
The Alcohol and Drug Foundation has provided rough timelines for the duration for drugs to remain in the human body.
Cannabis depends on the usage, for infrequent users it will remain in the salvia for 12 hours. However, for frequent users the salvia will typically test positivity up for 30 hours. Users can expect their urine to test positive for between 10 and 30 days.
There is often public debate about this finding, an example of which can be found here.
Within the “party drugs”, MDMA remains the longest compared to cocaine and ketamine.
Methamphetamine will remain in salvia for up to 2 days and in urine for 2 to 5 days. Interestingly, benzodiazepines will last significantly longer in urine (up to 2 weeks) compared to in salvia (less than 24 hours).
As with all scientific research, the results will depend on the reliability of the experiments and data. It is not advised to strictly follow these timelines as a multitude of factors will influence the length a drug will remain in a person’s system. Commonly the following factors can have the largest impact:

The criminal offence of Driving with illicit drug present is a “strict liability” offence, meaning that a lack intention to drive with drugs present cannot be used as a defence. The prosecution must prove beyond a reasonable doubt that the driver:
There are limited defences available if the elements are proven, these include:
Morphine is a unique case. Medicines and painkillers commonly contain morphine, and due to this the law has allowed for a special exception for driving with morphine present if consumed for medical purposes only. However, this consumption must be in line with the prescription, purchased from a pharmacy and taken in accordance with the manufacturer’s instructions.
MOBILE DRUG TESTING
The police are empowered to test drivers on NSW roads for the presence of drugs via Mobile Drug Tests (MDTs). The usual situation a driver will face is as follows:
MDTs are the initial salvia tests, which if positive will mean the driver will be taken to a police drug bus or police station for a secondary test. If the secondary sample is positive, the driver will likely be suspended from driving for a period of 24 hours. The secondary sample is sent to a laboratory for further testing, and the result may take months to return. If the secondary sample is positive under laboratory conditions, the driver may be charged with Driving with illicit drug present.
Once the secondary sample is returned as positive, the police officer is empowered to either issue a penalty notice or a court attendance notice for a first-time offender. However, repeat offenders must receive a court attendance notice.
PENALTIES
Following the penalty notice, first time offenders will be required to pay a $603 fine and will be suspended for three months. If an offender is issued with a court attendance notice, the following penalties apply if a conviction is recorded:
First offence:
Secondary and subsequent offences:
What happens if the police officer believes a driver is affected by drugs? The police will consider the criminal charge of Driving under the influence of drugs.
This will require the police officer to record their observations of the driver and issue the driver with a court attendance notice. The prosecution must prove beyond reasonable doubt that the driver:
PENALTIES
The maximum penalties for this charge are serious:
Due to the nature of this criminal offence, the defences are limited and will depend on the facts of each case.
