Alcohol, Mouthwash & Tinctures: What you need to know


Refrain from breath testing if you've consumed alcohol. Alcohol can cause elevated fermentation scores and repeat exposure to alcohol in the breath may harm the sensors in your device.


Avoid using a mouthwash within an hour of breath testing, as many mouthwashes contain alcohol which can cause elevated f-scores. This is especially important on Challenge / Discovery days - completely avoid mouthwash before your test.


When it comes to taking medications that contain small amounts of alcohol (such as tinctures), generally you consume these in very small quantities i.e. a number of drops per dosage. As a result, you needn't worry too much about the effect this may have on your breath test results, though if you have concerns or suspicions that your results are driven up when you take a breath test too soon after consuming your tincture, simply space out the medication and your next breath test by an hour or so.

Hope this helps!
