The smell of raw cannabis in a vehicle gives police probable cause to search it, the Illinois Supreme Court ruled last week.
The ruling comes months after the court ruled the smell of burnt cannabis does not give police probable cause to search a vehicle, drawing a fine line for motorists and police to follow when evaluating legal possession of cannabis.
“The odor of burnt cannabis suggests prior or current cannabis use, and the odor of raw cannabis suggests that cannabis is currently possessed in the area where the odor is detected. Different laws are implicated based on those inferences,” Justice P. Scott Neville, a Democrat, wrote in the majority opinion.
The 4-2 ruling by the court, with Republican Justice Lisa Holder White abstaining, found that an Illinois State Police trooper conducted a legal search of a car in which Vincent Molina was a passenger in December 2020, after the driver was pulled over for speeding on Interstate 88 in Whiteside County.
According to court documents, the trooper said he smelled raw cannabis in the vehicle and initiated a search. The trooper then found multiple joints in a cardboard box in the car’s center console and cannabis in a sealed plastic container in the glove box. Molina was charged with a misdemeanor for illegal possession of cannabis.
A circuit court initially ruled in Molina’s favor, finding the search was unreasonable because Illinois law allows people over age 21 to possess recreational cannabis. But an appellate court and the Illinois Supreme Court disagreed with that ruling, citing the state’s laws for how cannabis should legally be possessed in a vehicle.
Illinois law requires cannabis to be in a “sealed, odor-proof, child-resistant cannabis container” when in a car and for it to be “reasonably inaccessible while the vehicle is moving.”
Neville wrote the trooper made a “reasonable inference” that the smell meant cannabis was illegally possessed.
“While cannabis is legal to possess generally, it is illegal to possess in a vehicle on an Illinois highway unless in an odor-proof container,” Neville wrote. “The odor of raw cannabis strongly suggests that the cannabis is not being possessed within the parameters of Illinois law. And, unlike the odor of burnt cannabis, the odor of raw cannabis coming from a vehicle reliably points to when, where and how the cannabis is possessed — namely, currently, in the vehicle, and not in an odor-proof container.”
The Illinois Supreme Court unanimously ruled in September, with White abstaining, that the smell of burnt cannabis does not indicate a crime has been committed and does not give police probable cause to search a vehicle. Supreme courts in other states have also issued rulings placing limits on when the smell of cannabis gives probable cause to search a vehicle.
Illinois lawmakers have also sought to enshrine limitations on vehicle searches based on the smell of cannabis into state law. The Senate passed a bill in 2023 that would prohibit police from searching a vehicle based on the smell of burnt or raw cannabis, but it stalled in the House pending resolution of the court cases.
