Asking for a friend as Im military and unable to do dabs.

With a BMI of 21.8 and a BMR of 1592 cal/day and a piss test after the holidays around the 4th/5th, would my buddy be good to do dabs just this once? The dabs are from a dispensary in Oregon, pretty good quality. Hes never dabbed before and would only do it just this once. Based off that info, would be be fine 2 weeks?

should be fine, but you can't guarantee it that short of a time.
Generally using once takes less than a week to go away but again, two weeks isn't long enough to be confident guaranteeing he'll be fine.

Hair sample takes longest to go away but generally a.month to be on safe side

if marijuana, 30 days sir

Why not just wait until after the piss test?

I have smoked every day for a year drank water and worked out for a day. Took a piss test barely passed. I have a friend who stopped smoking and 2 months later still failed.

The sits in fat cells so the fatter you are the longer it stays in your system

Dab dance?

Ill piss dirty for fuckin years to come lol

wheres the follow up. did he pass. fail?

It is really simple. When you increase your H2O intake, you dilute the other chemical present in your urine.
