Background
Aaron Michael Painter and his fiancée, Ali Smith, were making marijuana concentrate in their home using a process that involved extracting oil from marijuana with butane. Butane vapor allegedly accumulated and ignited, causing an explosion and fire. Smith died, while Painter and their seven-year-old daughter suffered severe burns.
The prosecution charged Painter with involuntary manslaughter, delivering or manufacturing marijuana, and third-degree child abuse. Painter moved to dismiss all three charges, arguing that the Michigan Regulation and Taxation of Marihuana Act protected his in-home processing of marijuana and immunized him from prosecution. The circuit court concluded that butane extraction was not protected “processing” under the act and denied the motion.
The Court’s Holding
The Michigan Court of Appeals held that butane extraction qualifies as “processing” under the MRTMA because the statutory definition includes extracting or otherwise making or preparing marijuana concentrate. The court also concluded that the act’s prohibition on butane extraction “within the curtilage” of a residential structure does not encompass the interior of the home. Because the limited record indicated that Painter was processing marijuana at home within the act’s personal-use and quantity limits, the court held that MRTMA immunity required dismissal of the marijuana charge.
The court nevertheless held that MRTMA immunity does not bar the involuntary-manslaughter and third-degree child-abuse charges. Those offenses can apply when otherwise lawful conduct is performed with criminal negligence or recklessness, and their application is not inconsistent with the MRTMA. The prosecution therefore may attempt to prove that Painter conducted the butane extraction negligently or recklessly, causing Smith’s death and the child’s injuries.
Accordingly, the court affirmed the refusal to dismiss the manslaughter and child-abuse charges, reversed the refusal to dismiss the marijuana charge, and remanded for further proceedings. It noted that immunity could cease to apply if later-developed facts showed that Painter exceeded the statutory quantity limit or was not processing the marijuana for personal use.
Key Takeaways
- Butane extraction inside a person’s residence can constitute protected “processing” under the MRTMA.
- The MRTMA’s reference to the “curtilage” of a residence does not include the home’s interior.
- MRTMA immunity does not shield criminally negligent or reckless conduct merely because that conduct occurred while processing marijuana.
Why It Matters
The decision separates immunity for marijuana activity itself from liability for the manner in which that activity is performed. A person complying with the MRTMA cannot be prosecuted solely for protected in-home processing, but the act does not eliminate generally applicable criminal liability when negligent or reckless processing causes death or injury.
The ruling also clarifies that, under the statutory language, butane extraction is “processing” and that the act’s location-based exclusion for extraction within residential curtilage does not extend into the residence itself.
