My scientific way for sending weed (never tested, lol): Put weed in shrink wrap, sealed, freezer type plastic. Put it inside bottle of shampoo and fill bottle with shampoo. Put some other bottles and colognes in there too, and overnight ship it via FED EX or UPS (not US Mail). If you're flying somewhere it's there when you get there the next day. Pretty suave! I don't know if it would work, but it has a lot of credibility to it. UPS doesn't really care since I'm sending it to myself, I think. Since it's overnight shipping, it won't sit anywhere it shouldn't be. People can't take shampoos and stuff on planes anymore, anyway, so it is reasonable to avoid any searches or to have dismiss any probably cause, whatsoever. What do you guys think or know? Why do people try to trick the USPS when they can use Fed ex or UPS instead and have less to worry about?
