A Maryland appeals court has ruled police officers can no longer stop people based on the smell of marijuana alone, further limiting when the distinctive odor can justify police actions.
In a decision issued this week, Maryland's second-highest court found that a whiff of marijuana does not give police a legal reason to stop and investigate someone.
Police need "reasonable suspicion" that a crime is being committed before they can detain someone for even a short period of time.
Marijuana smell is no longer enough to meet that standard because small amounts of the drug are decriminalized, the court ruled.
"Because an officer cannot tell by the smell of marijuana alone that a person is involved in criminal activity, we hold that the odor of marijuana, by itself, does not provide reasonable suspicion to conduct an investigatory stop," Judge Kathryn Grill Graeff wrote in the opinion.
