Plain-language change summary

The latest version of Bill SB 599 clarifies the definition of intoxicating cannabinoids by specifying that a product must contain more than 1.75 milligrams per container to fall under this categorization. Additionally, it maintains that businesses holding a license for both hemp and marijuana processing do not need to destroy certain intoxicating cannabinoids formed during processing. This matters because it sets clearer guidelines for producers and helps regulate products, which can enhance consumer safety and ensure that the market for hemp-derived products is better defined.
