Airport full-body scans..

Can they detect things besides metal/bombs? Say, if some patient had (accidentally, of course..) forgot a doobie in their jacket pocket. Do those things pick up organic material, or drug residue/smell? I doubt they're that hyper-sensitive, but the government is unpredictable. Just sayin, tis the season to travel..

A doob should pass just fine. They do use smell detectors ... outstanding ones ... but they go woof. cn
