Illinois moves to limit the vehicle search based on cannabis smell

Legislators in Illinois are increasing for legislation in order to restrict the ability of the law enforcement authorities to carry out vehicles based exclusively on the smell of cannabis. This step aims to clear up concerns about bourgeois freedoms and to align police practices with the state's cannabis legal laws.

Legislative efforts to change search protocols

In April 2025, the Senate passed Senate Bill 42 (SB 42) in Illinois, which determines that the smell of cannabis alone cannot be a probable reason for the police to search for a vehicle. In the draft law sponsored by Senator Rachel Ventura (D-Joliet), the criminal proceedings are to clarify in this matter according to contradictory court certificates. SB 42 is now waiting in the House of Representatives and asks if they are approved to sign the governor's signature to become law.

Background: contradictory court decisions

The legislative advance comes up with the recent decisions of the Supreme Court in Illinois, which have created ambiguities in relation to the legality of the vehicle search on the basis of cannabis smell.

• People v. Redmond (2024): The Court ruled that the smell of burned cannabis alone does not provide any probable reason for a search for a vehicle and recognizes that the smell could result from legal consumption and does not necessarily indicate criminal activities.
• People v. Molina (2024): Conversely, the Court of Justice found that the smell of raw cannabis, which is based on a vehicle, provides a probable reason for a search, and it is clear that it indicates that cannabis is not stored in a odor-proof container, as is necessary according to state law.

These different decisions have led to confusion between the law enforcement authorities and the public, which has caused the explanation of legislative clarification.

Implications for civil freedoms and law enforcement authorities

The supporters of SB 42 argue that it can lead to violations of data protection rights and the disproportionate target for certain communities if you are only looking for the cannabis smell for vehicles. They claim that the legislation will contribute to the fact that the search is based on significant evidence of illegal activities.

The law enforcement authorities say that the draft law could hinder their ability to recognize and prevent the illegal transport of cannabis, especially if it is not stored in accordance with state regulations.

Next Steps

In the course of the legislative procedure SB 42, the stakeholders on both sides continue to discuss the balance between effective law enforcement authorities and the protection of individual rights in the context of the developing cannabis laws.
