Can random roadside saliva tests detect the presence of prescription drugs or other medication?
No. The saliva test only detects the presence of THC (cannabis), Methylamphetamine (speed) and MDMA (ecstasy). It does not detect the presence of prescription drugs or common over the counter medications, such as cold and flu tablets, sinus medication (e.g. Sudafed), asthma or ADHD medication. However, drivers impaired by other drugs (either prescription or illicit) will continue to be prosecuted under section 47 of the Road Traffic Act 1961 for the existing offence of driving under the influence of an intoxicating liquor or drug – commonly referred to as ‘DUI’. This offence carries severe penalties and drivers may be fined up to $1,200 for a first offence, in addition to a period of licence disqualification, demerit points or even imprisonment in some cases (refer to question 9 for further information). If you are unsure about the side effects of your medication or any impact it may have on your driving ability, please consult your doctor.
