How far back can a saliva swab test detect alcohol use?

Question

I drank an 8 oz bottle of brandy on Sunday, and took a saliva swab test on Wednesday- will this show up on the swab test?

Answer 1

I would say you're good. There aren't many tests done to calculate how long it lasts, mostly because alcohol is legal if you're the right age. I know I did a medical thing to calculate how long it stays in your blood stream. You can usually clean it out in 48 hours, so since you only had 8oz and its been much longer, I can't imagine anyone being able to find it in your blood much less your saliva.
