if you must bring it, keep it on your person, not in your checked luggage where you dont know if a dog is back there sniffing or not, and not in your carryon which they could search for any reason at the X ray station.
wear compression shorts, sack it up.
if time permits, send a buddy through security first, have him text you a "we're good" if he sees no dogs and if the security is pretty lax.
best idea of all: don't bring weed, find some there. You probably wouldnt get caught bringing it through the airport, but trying to convince yourself of that from the time you get to security to the time you walk out of the other airport is no fun at all.
one more thing. do NOT under ANY CIRCUMSTANCES bring your pipe, grinder, hell, even papers. Buy your smoking apparatus at your destination, cause otherwise it is just another thing that can get you caught. And make sure that you have no metal on you when you go through that metal scanner, because if they have to do the personal body scan with the handheld metal detectors, not only might they smell your pot when their face is by your nuts, but you also will have the most nervous ass look on your face the whole time.
