Eh, I don't see a big deal about pinching a few times, but don't use your parents stash as your own. Its like bummin' a cig. Most people wouldn't make a huge deal over 1-2cigs a week. I'd only take enough to get high though. One kid I knew his parents toked and we took from their stash, but it was only a tiny bud, like .2g, it was just kinda floatin' around in their shoe box that was filled with like 20 bags that used to have weed.

A few grams a week though...dude buy your own. Maybe you just got ripped off. I'd be super pissed to have a few grams missing every week from my stash. Like hell...if someone took 2-3 grams from me a week then my stash would be GONE way faster.
