meh...so much paranoia floating around...
maybe im lucky but ive flown to & from at least 20 different airports with weed on my person going thru standard security, secondary metal detectors, pat down & the new "puffers" (you arent required to enter this "security device" if you dont want to, simply say that youre afraid it'll cause cancer in the future and they are required to screen you another way)
yes, Fed time is no joke (but Matthew, please dont talk about RICCO if you know not of what you speak...spreading false information is no bueno) but one must understand that the FAA isnt ACTIVELY searching for people with personal stashes, they could care less about your dub sack under your nut sack...
also, TSOM you may see dogs at airports, but 95% of the time theyre not "drug dogs", theyre "bomb dogs"...dogs you see scratching around while they sniff are "drug dogs" while the dogs you see on the straight and narrow just sniffing are "bomb dogs" (my significant other trains dogs for obedience & "searching"/"sniffing" for the local LEO)
if youre a valid medical marijuana patient, just toss it in your check in bag...IF they come across it, you simply say that you forgot it was in there & provide your paperwork...yeah, they may keep your stash, but they cant arrest you
just my $0.02...
(PS - all of this info supplied applies to DOMESTIC FLIGHTS...flying international with herb is just crazy talk)
