Should I chance it? PLEASE HELP

I have a drug test for a new job scheduled for the 21st of this month.

I quit smoking last monday on the 30th of june. But then I ended up smoking about 4-5 hits from a pipe on the 5th this past saturday. So basically I will have about 15-16 days of being totally clean and would only have smoked one small amount on the 5th. So basically one time in about 21 days. last time being 16 days prior.

I wouldnt call myself a very heavy user but I had a steady smoking schedule for about 3 months prior to quitting. I would smoke a bowl every night before bed. It was a 50/50 mix of regular weed and some very good stuff depending on what I had.Some nights the good stuff some nights the regular. Never any more than that....one bowl a night to help with sleep and to chill.

I am 23 years old 6ft 235 pounds. 16.7% bodyfat.Checked with calipers at the gym. I work out a lot but have not been lately in the past month (been busy) or so...but my bodyfat is average or a little below.

I really need some advice and would really appreciate some input.

BTW I have passed a drug test in the past with the same smoking routine etc. in exactly 3 weeks.

thanks a lot for the help guys

Dude you should be completely fine, and it will help even more if you just work out a few times between now and then. I've smoked before on a Friday and passed a drug test on Monday morning, it's no big deal if you only do it once, especially of you have three weeks time. You're straight.

Im thinking i might be ok. But that smoke on the 5th might just fuck me over.

Did you read my post? I was a steady once a day smoker prior to quitting

This is a really solid job that I have went to college for (23 bucks an hour)
I am worried as hell.
