How bad will a bit of a binge set me back?

Hey all. I decided it was about time I get my lazy us up and look for a job a few weeks back. Turns out all the places I felt like working at drug test. So, I of course have to stop toking if I want to pass a drug test. So, after a long night of many bongs I started my break.

I lasted 20 days, I was an everyday toker for about 2 weeks before starting the break, my main decision to take the break was my decent into daily smoking, I didn't want to abuse the plant like that. Before that I was an every 2 or 3 day smoker, so, being a skinny teenager I was probably about clean by the 20 day mark, but then a friend of mine got a large quantity of very good bud and I finally broke down and smoked. I thought I might get a job at a place that didnt drug test after speaking with managers there twice, and still havent heard anything, so it looks like ill have to stop smoking again to pass a pisser.

How long do you all think it will take for me to get clean, if I smoke about 2 grams of bud over 4 days after being almost clean? Will I need to take another 3 week break or whatever, or should a week or so do it?

There have been some on this forum that have taken 60 days to get clean. Very small percentage but it is true. Your best bet is to get some home test kits and test yourself. For pre-employment you can just sub with quick fix. Read the threads, there are great experts on this forum as FBR and Killerweed. But my advice is just to quit period. Is it really worth all the stress and anxiety you will expirence just thinking about it?
