What is the longest time peth can detect alcohol?

Depends on what kind of alcohol consumer you are as drunks will test positive much longer than a one time user and at much higher levels. Even still every person is physically a bit different and some will fully metabolize in a few days and others even longer but most use the 60 hour rule that's fairly reliable for ordinary drinkers, but like I said with drunks and alkies its a whole new ball game.

Got a party or event close to your test? Skip the alcohol!

It is a peth test. Last drink 7 weeks ago.

You should be in good shape after 7 weeks unless you were an everyday heavy drinker before but I don't think it goes back beyond 3 to 4 weeks.

Thank you!
