Synthetic Marijuana

Did you know that hemp can be intoxicating? Or that synthetic marijuana products, including those sourced from hemp, are now prohibited in the State of Montana per House Bill (HB) 948?

Synthetic marijuana products became illegal on May 22, 2023, when Governor Greg Gianforte signed HB 948 into law. This new law impacts any person or business that manufactures, processes, or offers a synthetic marijuana product for sale to consumers.

A synthetic marijuana product is any product that contains synthetic cannabinoids.

Synthetic cannabinoids are cannabinoids, intoxicating or non-intoxicating, produced through a chemical synthesis in a laboratory setting or with biological agents such as genetically modified yeasts or algae.

There is little research available concerning the adverse human health effects of these products.

Hemp biomass containing high levels of naturally occurring CBD is extracted and concentrated into legal, non-intoxicating CBD isolate.

This CBD isolate is then mixed with hazardous chemicals in an unregulated setting to convert the CBD into nearly any synthetic cannabinoid, intoxicating or otherwise.

This process also creates unintended byproducts which have not been studied for human health effects.


  • Look for products that contain or advertise common synthetic cannabinoids (e.g. delta-8-THC, delta-10-THC, THC-O-acetates, THCV, THCP, HHC, HHC-O-acetate, HHCP, and CBN.)
  • Products that produce a feeling of being “high” or promote intoxication that sold in locations other than licensed dispensaries.
  • Ask for test results to confirm the absence of synthetic cannabinoids. If test results can’t be produced, consumers should avoid these products.
