Smokers!! How long does weed stay in your system??

I am not a frequent smoker. It’s been over a year since i smoked but on vacation I had about 3-4 hits of a blunt. I’m job hunting so I’m wondering how long this will be in my system for. I’ve heard about two weeks but what about for a hair test??

If you are not experienced or against smoking please keep it to yourself and disregard this post :)
