For those of us that have several decades of lifes experiences behind us, its painfully obvious which of the posters are children and which are responsible adults.
Generally, if a poster is asking questions about how much for this bud, or hiding pieces in mommy and daddy's house, how to roll a joint, or commenting on "what grade they are in", and such as that, its a real good bet that they are just another child.
Then there are those that tell of smoking 3 or 4 blunts, and/or smoking an 1/8 in an evening.........WTF??? What kind of lawn clippings are they smoking??
2 or 3 bong hits off decent bud will put *most* folks into couch lock, period. More than that and you will start hearing colors and seeing sounds.
Ok... all that being said, lets see who tries to tell me that I am full of crap.
