I don't pass up the opportunity.
People always complain about people "Wasting money" on weed. But lets see, personally, I can make 25 bucks, a "quarter", last me a couple weeks, and it doesn't take much to get me high.
In that couple of weeks, I've probably spent $25 on even more useless shit I don't need. At least I get some form of entertainment out of weed. But then again, I've never been in some sort of money situation where spending $25 on things I don't need has ever been a problem.
I've spent much more on gadgets and toys that I get bored of within a week.
