Quick 'do you think ill pass' question

First off, i know the only way to be sure is to take the test, i just want opinions. I used to smoke a good deal, like everyday or every other day, but that stopped about a week before 4/20, with 4/20 being heavy. Around 3 weeks ago I just stopped smoking all together. And on Sunday night i smoked a bowl and a bong rip. I'm a skinny guy. 120 pounds 5'8. tall and lanky, like no fat on me. While I'm not physically active, im not physically inactive. This weekend I might have a drug test, what do you think my chances are of passing without diluting or certo?

Slim chance bro, you atleast need to give that another 5 weeks to get out of your system entirely...yet if you did that it might still show signs of THC in your blood stream. I would suggest using Certo or Diluting if you don't want to get Caught.
