There is always a chance of a surprise UA while on probation. You should also be aware that EtG testing can indicate alcohol use up to around four days from consumption. In fact, it is so sensitive you can actually use an alcohol based hand sanitizer the day of the test and test positive because of it.

You need to decide whether or not you want to play games with the system or do what you need to do to get yourself through probation successfully.

It's your life man.
