If I drank 108 hrs ago will I pass the EtG test, I'm 5ft 10 weigh 175lbs and I'm 40 years old

Depending on the analysis method, alcohol may be detected up to 80 hours or even up to a week.

Best bet is to get some help kicking the habit.

Based on the hours since you drank, you should be okay. But we can only guess. That's the best guess I can give.

What do you stand to lose if you fail?

If you have a long history of heavy drinking you still might fail.

But if even if you pass this time... doesn't mean you will get over the next time. The law of averages is against you.
