What it does

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

Current law designates tetrahydrocannabinols as a Schedule I controlled substance. Current law specifies that THC does not include cannabidiol (CBD oil) in a form without a psychoactive effect that is dispensed by a pharmacy or physician approved by the Controlled Substances Board or that is possessed by an individual who has documentation from a physician that the CBD oil is used to treat a seizure disorder. This bill specifies that the documentation must be a certification issued by a physician within the previous year stating why the individual possesses the CBD oil and that the individual may possess CBD oil to treat a medical condition, not just a seizure disorder.

Under current law, if a substance is designated, rescheduled, or deleted as a controlled substance under federal law, the controlled substances board must similarly treat the substance under state law within 30 days unless there is an objection, in which case the board must follow certain other procedures before the substance is designated, rescheduled, or deleted. This bill requires that, if CBD oil is rescheduled or deleted as a controlled substance under federal law, the board must similarly treat CBD oil under state law as soon as practically possible, but within 30 days, and does not allow for an objection.
