The Michigan Supreme Court recently issued a significant decision in People v. Hess, holding that judges generally cannot prohibit individuals on probation from using marijuana (known as cannabis in Canada) if that use is otherwise lawful under Michigan’s recreational marijuana law. The Court concluded that the Michigan Regulation and Taxation of Marihuana Act (MRTMA) protects lawful marijuana use and that probation conditions cannot automatically override those statutory protections simply because marijuana remains prohibited under federal law.

In reaching its decision, the Court overturned prior interpretations that allowed blanket marijuana bans as a standard condition of probation. This ruling has important implications for individuals facing criminal charges and those currently serving probation, as it may affect the conditions courts can lawfully impose in future cases.

Because this is a recent Michigan Supreme Court decision, courts will likely continue interpreting how People v. Hess applies in future probation cases.

Does This Mean Everyone on Probation Can Use Marijuana?

Although the decision in People v. Hess expands the rights of many probationers, it does not create a blanket right to use marijuana while on probation. Instead, the ruling prevents courts from automatically imposing a marijuana ban solely because someone has been convicted of a crime. Each probation order is unique and judges may still have authority to restrict marijuana use when the circumstances of a particular case justify doing so.

For example, marijuana restrictions may be appropriate when they are reasonably related to a person’s rehabilitation, substance abuse treatment, public safety or a drug offense. The Michigan Supreme Court intentionally left many of these issues open for future cases, meaning additional guidance will likely develop over time. Until then, individuals on probation should continue complying with every condition of their probation order and consult an experienced criminal defense attorney before assuming the ruling changes their legal obligations.

How This Decision Could Affect Future Cases

The Michigan Supreme Court’s decision is expected to influence how probation conditions are handled throughout the state. It’s possible that defense attorneys will ask courts to modify existing probation orders that include automatic prohibitions on lawful marijuana use, particularly when those restrictions are based solely on an individual’s probation status.

Going forward, judges will likely need to evaluate whether a marijuana restriction is appropriate based on the facts of each case rather than imposing a standard prohibition across the board. The ruling may also prompt prosecutors, probation officers and trial courts to revise their approach to probation supervision and enforcement. In some cases, individuals accused of violating probation for marijuana use may have new legal arguments if their conduct was otherwise lawful under Michigan law.

For example, a court may reach a different conclusion depending on whether marijuana use is reasonably related to a person’s rehabilitation, substance abuse treatment, or the underlying criminal offense.

Protecting Rights During Probation

The Michigan Supreme Court’s decision in People v. Hess may expand the rights of some individuals on probation, but it does not automatically change every probation order currently in effect. Before using marijuana while on probation, it is important to understand how the ruling applies to a specific case.

Existing probation conditions remain legally binding unless they are modified by the court. An experienced Michigan criminal defense attorney can review probation terms, explain how this decision may affect an individual’s rights and seek appropriate modifications when warranted.
