How Long Do Drugs Stay in your Saliva?

In New South Wales (NSW), the police have the power to conduct drug tests on drivers, both on the roadside and at police stations, in order to detect the presence of certain drugs in a person’s system. The tests are typically conducted using a saliva sample, which is analysed for the presence of drugs such as THC (the active ingredient in marijuana), cocaine, amphetamines, and opioids.

The police can conduct drug tests in a number of situations, including during random breath testing (RBT) operations or if they suspect that a driver may be under the influence of drugs. The tests are designed to identify drivers who are impaired by drugs and may pose a risk to themselves and others on the road.

If a driver tests positive for drugs, they may face penalties such as fines, license suspension, and even criminal charges. In some cases, the police may also impound the driver’s vehicle. The police must follow specific guidelines when conducting drug tests, including following proper testing procedures and ensuring that drivers are informed of their rights.

Drugs can stay in your saliva for different lengths of time, depending on the type of drug and various other factors. Some drugs, like marijuana, can be detected in saliva for longer periods than others.

Here are some estimated detection times for common drugs in saliva:

Marijuana

Up to 24-48 hours, or even longer for heavy users.

Cocaine

Up to 1-2 days.

Methamphetamine

Up to 2-3 days.

Opiates

Up to 1-2 days.

Benzodiazepines

Up to 2-3 days.

These are just general estimates, and detection times can vary based on factors such as individual metabolism, frequency and amount of drug use, and the sensitivity of the drug test being used. Drinking plenty of water and practicing good oral hygiene (such as brushing and flossing regularly) can also help to flush out drugs from your saliva.
