The Consumer Healthcare Products Association (CHPA) today applauded Idaho Governor C.L. "Butch" Otter for signing into law real-time, stop-sale technology called the National Precursor Log Exchange (NPLEx) which allows check-out clerks to block illegal pseudoephedrine purchases right at the point of sale and provides law enforcement with valuable criminal data up to the minute. The legislation--Senate Bill 1309--was sponsored by Senator Joyce M. Broadsword (R- District 2).
