Also, ChillyP had an excellent idea in my other thread:QuoteIt would be pretty easy to thwart electronic sniffers I think, especially if there was a concerted effort. Throw a gram of finely powdered offender into a blue boxes near major shipping hubs on a regular basis. Everything gets contaminated (not quite, but you know what I mean). If this model of drug distribution ever scales up, I think they will focus on cracking down on the mail though. Then again, given the financial situation faced by the post, they may be limited anyhow.LEO. Checkmate.
