I am a 32 year old femalefemale and 110 lbs. I drank 1 glass of wine and approx 3 shots on wed ending at midnight. How long until I pass an EtG test?

Why?

I just found out I will be placed on probation and I'm assuming I will be getting drug tested

Conditions of the probation should not take effect until after it is placed upon you. Meaning if you don't have probation yet... then you aren't barred from drinking yet.
