If alcohol in mouthwash can make you fail a breathalizer or what about inhailor from asthma?

It is possible for alcohol in mouthwash to cause a false positive on a breathalyzer test, but it is unlikely. The amount of alcohol in mouthwash is typically very small, and it is quickly absorbed by the body. However, if you drink a lot of mouthwash in a short period of time, it is possible that the alcohol content could be high enough to trigger a false positive. However, the amount of alcohol absorbed from inhalers is negligible and would not be enough to cause a false positive on a breathalyzer test.
