Frequently Asked Questions

General Information

What is "industrial hemp"?

According to the California Food and Agriculture Code section 81000 (a)(6):

"Industrial hemp" or “Hemp” means an agricultural product, whether growing or not, that is limited to types of the plant Cannabis sativa L. and any part of that plant, including the seeds of the plant and all derivatives, extracts, the resin extracted from any part of the plant, cannabinoids, isomers, acids, salts, and salts of isomers, with a delta-9 tetrahydrocannabinol concentration of no more than 0.3 percent on a dry weight basis.

Industrial hemp is also defined in the California Health and Safety Code Section 11018.5.

What is the difference between industrial hemp and cannabis/marijuana?

Cannabis is defined in California Business and Professions Code (BPC) Section 26001(f). The BPC section 26001(f) definition explicitly states that cannabis does not include industrial hemp.

For information on the cultivation of medical and adult-use cannabis, contact CDFA's CalCannabis Cultivation Licensing Program.

Is growing industrial hemp legal in California?

Division 24 of the California Food and Agricultural Code provides for the cultivation of industrial hemp by registered growers, hemp breeders, and established agricultural research institutions.

Is industrial hemp federally regulated as a controlled substance?

The Agriculture Improvement Act of 2018 (2018 Farm Bill) , effective January 1, 2019, removed hemp from Schedule I of the federal Controlled Substances Act. Thus, hemp is no longer federally regulated as a controlled substance.

What are the current federal laws and regulations regarding industrial hemp?

The Agriculture Improvement Act of 2018 (2018 Farm Bill) was signed into law by the President on December 20, 2018. The U.S. Domestic Hemp Production Program was established by the U.S. Department of Agriculture (USDA) through an interim final rule on October 31, 2019. This rule provides the requirements for State and Tribal regulatory plans submitted to USDA for review and approval.

Additional information regarding pending federal legislation is available on the Law Library of Congress website.

Does California have a state regulatory plan approved by U.S. Department of Agriculture?

CDFA has not yet submitted a proposed state regulatory plan to the U.S. Department of Agriculture (USDA) for review and approval but is in the process of preparing a plan for submission.

CDFA will notify the public via our electronic mailing list of when California’s regulatory plan is submitted to USDA for review and approval. You can sign up to receive e-mail updates from CDFA regarding industrial hemp by visiting CDFA’s subscription webpage, or by sending a blank e-mail to: join-cdfa_list_phpps_industrial_hemp@lists.cdfa.ca.gov.

Are California hemp growers subject to the cultivation requirements outlined in the federal interim final rule?

According the U.S. Department of Agriculture (USDA) Hemp webpage, hemp growers are not subject to the cultivation requirements outlined in the federal interim final rule if a state has an approved regulatory plan or is in the process of developing a regulatory plan. California is in the process of developing a state plan, and thus, California hemp growers are not currently subject to the federal interim rule. However, growers in states that do not have a pending or approved regulatory plan may apply for a USDA hemp production license. For information regarding federal requirements for hemp producers, visit USDA Hemp webpage.

Are growers licensed by the U.S. Department of Agriculture required to follow California state laws and regulations?

Regardless of any federal requirements, all hemp growers in California must comply with existing state laws and regulations as well as any local restrictions that may apply.

Established Agricultural Research Institutions

What is an "established agricultural research institution"?

Under California Food and Agricultural Code Section (FAC) 81000(a)(4):
"Established agricultural research institution" means any institution that is either:
(A) A public or private institution or organization that maintains land or facilities for agricultural research, including colleges, universities, agricultural research centers, and conservation research centers; or
(B) An institution of higher education (as defined in Section 1001 of the Higher Education Act of 1965 (20 U.S.C. 1001)) that grows, cultivates or manufactures industrial hemp for purposes of research conducted under an agricultural pilot program or other agricultural or academic research.

This definition remains operative until the date on which a state regulatory plan for California is approved and the definition is repealed on January 1 of the following year.

Once a state regulatory plan for California is approved, under FAC Section 81000(a)(4):
“Established agricultural research institution” means an institution of higher education, as defined in Section 101 of the federal Higher Education Act of 1965 (20 U.S.C. Sec. 1001,) that grows, cultivates, or manufactures industrial hemp for purposes of agricultural or academic research.
