Blood Drug Testing

How long does cocaine remain detectable in saliva using the mouthswab drug testing method?

1. fyi...24 hours in blood & 4 days in urine
2. Generally speaking, swab tests that test saliva can only go back about 72 hours maximum (there are also 24-hour and 12-hour tests). Also speaking generally, cocaine is completely out of your system in about 72 hours. Of course it depends on your metabolism, how much you've been using, etc. A good plan is to give it a week before your test--just to be safe--and if you're worried, you should drink A LOT of water to help flush out your system. That--among other things--is what's awesome about cocaine--it's out of your system pretty quickly. Even if they pee test you (which can trace things like marijuana from MONTHS back), the coke will be gone in like 3-4 days. P.S. If you can put water in your mouth before they swab you that helps too! ;) Good luck dude!
