Terahertz Scanners See Inside Sealed Packages

opticsorg writes "Japanese scientists have demonstrated a system that detects the presence of illicit drugs that are concealed within an envelope. Tests to date have shown that the imaging system can successfully detect and identify a range of substances including ecstasy (MDMA) and methamphetamine. The researchers are now working with companies to develop a mail screening system that could suit use in post offices and airports."

One of the best responses ever to this topic was penned by Senator Jim Inhoffe (R - OK). A constituent sent him a post card with no name, but a return address on it that said, "Legalize drugs." He had a staffer go down to the Senate gift shop and buy a postcard. He simply wrote "No." on it, signed it, and had it sent to the return address.
