A member asked:

I smoked weed on december 31 and drank acohol on january 20. will that come up on a drug test?

A doctor has provided 1 answer

It depends...: One instance of drinking 3 days prior will not show up in a blood alcohol screen. One instance of smoking marijuana 3 weeks prior will not likely show up. Regular utilization of marijuana can take 6-7 weeks before it will not show up in a urine drug screen.
