Stone Ridge, NY: Dogs trained to detect the presence of illegal drugs are most likely to provide false alerts in situations involving the search of a motor vehicle, according to the findings of a study published online in the journal Forensic Science International.
A team of researchers from the United States and Poland assessed the ability of trained drug-sniffing dogs to accurately detect the presence controlled substances - including marijuana, hashish, amphetamines, cocaine and heroin - in various environments.
Dogs were most likely to correctly identify the presence of contraband, particularly marijuana, during searches of individual rooms. If the dog had previous exposure to the room prior to the search, it was least likely to provide a false alert (83 percent correct identifications versus 10 percent false alerts).
Dogs were far less reliable in scenarios designed to mimic real-world traffic stops. In situations where dogs accessed the perimeter of a motor vehicle, the animals accurately alerted to the presence contraband only 64 percent of the time. Fifteen percent of the time dogs failed to recognize the presence of illicit drugs. Twenty-two percent of the time the dogs indicated that illegal drugs were present when they were not.
Drug dogs' failure rates were even more pronounced in situations where the animals had access to the inside of a vehicle. In this scenario, dogs correctly responded to the presence of contraband only 58 percent of time. They provided false alerts 36 percent of time.
Previous studies have similarly documented drug dogs' tendency to provide false alerts. In 2011, researchers at the University of California at Davis reported that the performance of drug-sniffing dogs is significantly influenced by whether or not their handlers believe illicit substances are present. That same year, a review of Australian government statistics, published in the Sydney Morning Herald, found that some 80 percent of drug dog alerts in New South Wales yielded no illicit substances.
In 2005, the United States Supreme Court ruled in Illinois v Caballes that an alert from a police dog during a traffic stop provides a constitutional basis for law enforcement to search the interior of the vehicle.

A Michigan couple get their child back, New Jersey gets its second dispensary, and Washington regulators get an earful over moves to do away with patient home grows under I-502 legalization. And much, much more. Let's get to it:
Last Tuesday, a judge allowed a medical marijuana patient to continue to use while on probation, even though her plea agreement strictly forbade it. The county attorney in the case had added a blanket condition to plea agreements prohibiting offenders from using marijuana regardless of whether they hold medical marijuana cards, but the woman's attorneys argued that the clause violated state law and that prosecutors could not legally prohibit probationers from using medical marijuana. The judge agreed. The county prosecutor is expected to appeal.
On Tuesday, advocates and doctors urged the state to add PTSD as a condition treatable with medical marijuana. The occasion was a public hearing at the Arizona Department of Health Services. The state currently allows marijuana for eight specified medical conditions. The department will make its decision by January.
Also on Tuesday, the ACLU of Arizona filed a lawsuit requesting that the courts officially rule that extracts are covered under the state's medical marijuana law. The suit was filed in a bid to protect the parents of a 5-year-old boy suffering from epilepsy from criminal prosecution for treating him with marijuana-derived oil. Extracts are currently in a legal gray area in Arizona, where police and some prosecutors say they are illegal and the Department of Health Services is still "developing guidance to clarify these issues," even though that guidance was supposed to be completed this month.
On October 16, Mendocino County announced it had released more records to the federal government related to the former marijuana grow permitting program that allowed growers to have up to 99 plants per parcel. The county was responding to a second set of federal subpoenas, this one for a "limited number" of records concerning the program. An earlier subpoena was much broader, but was fought by the county. The county and the feds reached an agreement in April to release some records, but with the names of participants redacted.
Also on October 16, the Selma city council banned dispensaries and imposed tight restrictions on medical marijuana grows. The Fresno County community will require growers to register, get building permits, and stay 1,500 from sensitive uses, and no outdoor grows are allowed. The new ordinance is a slight improvement on a 2010 ordinance that banned all medical marijuana uses in the city.
Also on October 16, word came that the Justice Department has abandoned some asset forfeiture proceedings against medical marijuana landlords. The US Attorney for the Central District of California, Andre Birotte, dropped at least four cases in October. But other US Attorneys in the state continue to pursue asset forfeiture cases, including pending cases against landlords for Harborside Health Center and the Berkeley Patients Groups.
On October 17, medical marijuana activist Lanny Swerdlow prevailed in a civil trial against anti-drug crusader Paul Chabot. Swerdlow had alleged false arrest and malicious prosecution after a 2007 incident at a Rancho Cucamonga meeting. The jury found for the false arrest, but not the malicious prosecution, and awarded Swerdlow $5,000 for past losses. They will meet again to determine punitive damages.
On October 18, the owners of a former Vallejo dispensary filed suit against the city alleging abuse of power, excessive force, and retaliation after it was raided by police last year. Daniel and Rhonda Chadwick, owners of Homegrown Holistic Cooperative, Inc., claim the city retaliated against them after Daniel Chadwick spoke out at a contentious city council meeting after a series of dispensary raids. Police in Vallejo raided at least six dispensaries there in 2012 even though the city had voted the year before to tax dispensaries -- not shut them down. All of those cases fell apart, but the damage had been done.
On October 17, the Westport planning and zoning commission approved a moratorium on dispensaries and producers. The moratorium would last for a year, while the community has a chance to wrap its head around "the newness" of recently issued state regulations.
On Monday, the Farmington planning and zoning commission passed a six-month moratorium on medical marijuana facilities. The commission wants town staff to have adequate time to research the new state regulations.
On October 22, the Marijuana Policy Project criticized Gov. Markell's dispensary plan. State law calls for three dispensaries, but Markell had delayed opening any dispensaries for the last two years after receiving a threat letter from federal prosecutors. Markell has now moved forward, but said he will support opening only one dispensary next year.
Last Thursday, state Attorney General Pam Bondi challenged a proposed ballot initiative for a medical marijuana constitutional amendment. The attorney general is required by state law to send initiatives to the state Supreme Court for review, but Bondi also attacked the initiative, saying if it passed, "Florida law would allow marijuana in limitless situations" and warning that it conflicted with federal law. The court will hear arguments on December 5.
Last Friday, Sen. Tina Muna-Barnes filed a medical marijuana bill. The bill would require that all medical marijuana come from Guam itself. Last month, Muna-Barnes introduced a resolution to decriminalize marijuana for medical purposes that won broad support at a public hearing.
On Sunday, the Guam Medical Association complained it hadn't been consulted. The association didn't take a position for or against, but said it thought it should.
On October 16, a Bolton town meeting decided to approve a moratorium on medical marijuana dispensaries and grow operations. The moratorium would prevent such facilities until June 30, 2014.
Last Wednesday, a Saugus town meeting voted to approve a moratorium on dispensaries. The moratorium will stay in effect until September 30, 2014, or until local zoning bylaws are adopted.
On Monday, Wareham voters approved a zoning law that allows medical marijuana treatment centers. The law replaces a temporary moratorium on such businesses that was voted in at the spring town meeting. The centers will be allowed in an "institutional district."
On Tuesday, Framingham selectmen gave the go-ahead for staff to take dispensary applications.There are at least a dozen proposals pending for dispensaries or grow operations in the city. A Special Town Meeting last week rejected a zoning bylaw and proposed overlay district that would regulate medical marijuana dispensaries and growing facilities. The town is developing a ranking system to rate applicants.
Last Friday, an Ingham County judge ordered an infant child returned to her medical marijuana using parents. Steve and Maria Green's daughter Bree had been removed by Child Protective Services last month, but the judge found no evidence of abuse or neglect. The parents agreed not to medicate around their children, but said that's how they've handled things all along.
On Monday, the state's second medical marijuana dispensary opened. The Compassionate Care Foundation opened in Egg Harbor, making it the first in South Jersey. The state legalized medical marijuana in 2010, but the Christie administration has made the roll-out excruciatingly slow. Now, though, things are starting to roll. A third dispensary is slated to open in a couple of weeks in Woodbridge Township, and the state Department of Health is in licensing talks with three other facilities.
Last Tuesday, two Dickinson residents entered conditional guilty pleas to marijuana possession, enabling them to appeal to the state Supreme Court that their out-of-state medical marijuana guards should have allowed them to possess marijuana in North Dakota. Their lawyers will argue that the medical marijuana recommendations should be a valid defense.
Last Friday, the panel charged with crafting rules for dispensaries met again. The legislature this year passed a bill to regulate the medical marijuana system statewide, and this was the panel's second meeting. It is expected to finish its work by December 1.
Last Tuesday, a poll found support for medical marijuana at 71%. The state has taken no action to approve the medical use of the plant, but perhaps some legislators will take heed.
On Sunday, Sen. Jeanne Kohl-Welles warned that the battle for homegrown medical marijuana is not over. State agencies charged with implementing marijuana legalization under the I-502 initiative have proposed eliminating patient grows under the state's medical marijuana program, but that effort has ignited a firestorm of criticism from patients. Now, they have at least one prominent supporter in the legislature.
Last Tuesday, 18 legislators cosponsored a medical marijuana bill. The bill, Senate Bill 363, would allow for dispensaries and home cultivation. Patients or caregivers could grow up to 12 plants and possess up to three ounces at a time. The bill has been assigned to the Senate Health and Human Services Committee, chaired by Republican Senator Leah Vukmir, but has not yet been scheduled for a committee hearing.
