if i took a drug test and it tested positive would it be able to tell what day i smoked weed or just that i have smoked weed in the last 30 days?

just that you smoked although a nice flush would get rid of that for you, if not drink lots of fluids cranberry juice if you do not want to go get a flush kit.

The test will just detect wether it is in your system.

also make sure you don't give them your first piss of the day, give that one to the bathroom.

Also it depends on how much you smoke, how long ago (if you smoke a gram a day, then going dry for a couple of weeks will help), and what type of shape you are in also.
Because it is stored in your fat, and when you get out for a run/walk/jog and start to burn that fat off, it is then getting rid of the stored up THC in your system.

Drinking cranberry juice and such helps, but if you over do it, your piss might be to watered down, and they reject it on that alone.

also i was in the military and did this a lot...get a bottle of Niacin from GNC and drink a gallon of water for a few days...you can make it into shakes or whatever. Within a few days of that your system will be spot free, and wont look watered down..

I'm a 7x a week smoker and certo worked. I just took a 1500mg of niacin for 2 days, took some B complex pills to make my piss yellow again and drank 2 packets of certo with gatorade 2 hrs before my test. I didn't smoke for 2 days.

I also drank a shit load of water and it worked.
