If a Gárda suspects a driver of drug driving, what additional test may they request?

When a Gárda suspects a driver of drug driving, they may request a saliva sample as part of the assessment process. Saliva tests are a practical and non-invasive way to detect the presence of certain drugs in a person's system. These tests are designed to quickly assess recent drug use, which is critical in situations where impairment is suspected.

Saliva tests can detect a variety of substances, including cannabis, cocaine, and opiates, making them valuable tools for law enforcement. This rapid testing contributes to road safety by enabling officers to make informed decisions about whether further action is necessary, such as an arrest or further investigation.

In contrast, blood and urine samples are typically used for different purposes. Blood tests can provide a more comprehensive evaluation of drug levels in the body but are more invasive and can take longer to process, which may not be suitable in immediate roadside situations. Breath samples are commonly associated with alcohol testing and do not provide information about drug use. Therefore, saliva samples are the most appropriate additional test in the context of suspected drug driving.
