If you’re new to Ontario’s Ignition Interlock Program or any provincial program across Canada you probably have a few questions. One of the most common concerns is whether everyday items, such as mouthwash, cough syrup, or even vanilla extract, can cause a “false positive” on an Ignition Interlock Device (IID).
It’s an understandable worry, especially if you’re relying on your device to stay compliant and get back on the road. The good news is that with the right knowledge and support from Smart Start Canada you can avoid unnecessary lockouts and drive with confidence.
Why Everyday Products Can Trigger a Reading
Many common items we consume or use contain alcohol, like ethanol or menthol. Vanilla extract, for example, can contain up to 35–40% alcohol the same type found in beer, wine, or spirits.
When you use these products and immediately provide a breath sample, your Ignition Interlock may register alcohol on your breath. While people often call this a “false positive,” it isn’t really false. The device is working exactly as it should it’s simply detecting residual alcohol from the product you just consumed.
Busting the Myth of False Positives
Government approved Ignition Interlock Devices in Canada use highly reliable, alcohol specific fuel cell technology. This means they are extremely accurate and do not mistake other substances for alcohol.
If alcohol is present even from mouthwash or cooking extracts the IID will detect it. The difference is that these traces are temporary. By rinsing with water and waiting a few minutes, the alcohol will usually dissipate, and you’ll be able to provide a clean breath sample.
Smart Start Canada Tip: Always rinse with water before testing. This simple step helps prevent failed starts caused by residual alcohol from everyday products.
