Is fucked up! Trust no one.
Man thats why I gave up dealing a long time ago, last time somone grabbed a little bud out of my personal stash when I was smoking through part of the deal (which you should never ever do) I went to the can, came back the bag had moved slightly, plopped it on the scale, it was off...I grabbed my machete from under the couch and beat him in the face with the blunt end...
But as ganj was saying, karmically, whos fault was that? That was mine, I let controll of the situation slip away, and now that poor guy has all types of scars on his face from teh blunt side of a machete. So I robbed myself, and hurt him through my STUPIDITY.
When you loose controll; you reap the harvest you have sown (pink floyd, animals)
