In case you're not a verteran in weed transactions, there's a little thing that some punk dealers out there do called 'lemon weighting'. Actually i don't know what it's called, but that's what it is. It's pretty much the equivalent of turning coke into crack. The dealer gets his stack and puts lemon juice in it to make it heavier. Apparently they think the people buying are blind or something, because there is a definite difference in amount. I learned this the hard way the other day. You can recognize lemon weighted weed by a couple of traits: 1) You can see white flakes or crystals on the weed. I first saw this in the bag and thought it was crack, but then after tasting it found that it was quite sour. 2) Some weed may be burnt/dead looking/not green. I'm pretty sure this is caused by too much citric acid. But you can see it pretty clearly. 3) There's not enough. I paid for a half ounce and barely got what looked like a quad. Seriously, i've bought half ounces for months, and i could tell right away this was bullshit. Check your shit before you pay!
