Reflecting the change in Washington State law making it legal for adults to possess small amounts of marijuana and use it in private, some law enforcement agencies are retraining their drug-sniffing dogs not to alert for marijuana.
Local stories include:
- Legal pot means big changes for state’s drug-sniffing dogs, KOMOnews.com, March 20, 2013 (video and text)
- Manuel Valdes, Pot on some police dogs' not-to-sniff list, News Tribune (Tacoma), June 3, 2013. (This AP story was picked up by many national and local news organizations.)
The Supreme Court has issued two dog-sniff cases this Term. In Florida v. Harris (Feb. 19, 2013), the Court unanimously upheld the admission of evidence found in a truck after an alert by a trained dog (who had previously been reliable). SCOTUSblog's summary of the case is here. In Florida v. Jardines (March 26, 2013), the Court found that using a drug-sniffing dog on the defendant's front porch was an illegal search.

Narcotics dogs do not always perform accurately. In fact, a study of Chicago-area traffic stops by the Chicago Tribune found that drugs were found in just 44% of the vehicles where dogs alerted—and in only 27% of the vehicles with Hispanic drivers. Dan Hinkel & Joe Mahr, Tribune analysis: Drug-sniffing dogs in traffic stops often wrong, Chi. Tribune, Jan. 6, 2011. An academic study about the same time "found that detection-dog/handler teams erroneously 'alerted,' or identified a scent, when there was no scent present more than 200 times — particularly when the handler believed that there was scent present." Explosive- and drug-sniffing dogs' performance is affected by their handlers' beliefs, UC Davis Health System, Feb. 23, 2011.

The current issue of the Oregon Law Review (available free in PDF) is a symposium on drug policy. It includes Jane Bambauer, Defending the Dog, 91 Or. L. Rev. 1203 (2013). The author says "This short essay makes the uneasy case for the narcotics dog. Those in favor of U.S. drug enforcement presumably need no convincing, but this Article intends to address the concerns of skeptics who worry about unjust drug enforcement, or who believe that criminalization is just plain bad policy. Dogs are just the first generation of a new set of law enforcement tools that can help us divorce criminal investigation from the bias and discretion that comes with traditional policing."
