California Marijuana Testing License

Does California Require Testing for Marijuana and Marijuana Products?

Yes. California requires cannabis testing laboratories to verify that the products are safe for human consumption and to provide information on the potency of the products being sold to consumers.

Cannabis has several medicinal benefits and considering that all medicinal products provide information about their potency and dosage, cannabis products are being required to meet the same standard. Regulations are being developed by international organizations for the adoption of standards and acceptable limits of specific compounds found in cannabis to ensure cannabis products do not compromise a person's immune system.

Also, the cannabis plant has a sponge-like behavior during cultivation, absorbing nutrients and components from the soil including heavy metals in the soil, pesticides, fungicides, and the plant growth regulators used. Residual solvents from these chemicals create potentially dangerous safety issues for cannabis consumers. Therefore, it is crucial that cannabis products are tested to avoid the contamination that may occur through the long journey from seed to plant processing before finally ending up as a packaged product on retail shelves.

The Department of Cannabis Control (DCC) mandates testing of all batches of cannabis products prior to their sale. Testing laboratories inspect cannabis products to ensure they are:

  • Contamination-free
  • Accurately labeled with cannabinoids and terpenes

Cannabis products in California must be tested for over 100 contaminants. Among these contaminants are 66 pesticides, 21 of which the state has zero tolerance for. According to the Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA), licensed cannabis testing laboratories must test cannabis goods for:

  • Cannabinoids and terpenes
  • Residual solvents and processing chemicals
  • Residual pesticides
  • Heavy metals
  • Microbial impurities
  • Mycotoxins
  • Moisture content and water activity
  • Foreign material

The DCC requires the batches of cannabis goods that fail testing to be destroyed by the distributor or remediated by a manufacturer. Remediation removes contaminants from a cannabis product. Only manufacturers are permitted to remediate cannabis products; however, the DCC must approve the remediation plan in advance. Remediated cannabis products may only be sold after they have been re-tested following remediation.

Does California License Independent Marijuana Testing Facilities?

Yes. In California, cannabis testing laboratories are required to be independent and third-party owned. Independent, licensed testing laboratories are responsible for collecting samples from licensed distributors for testing. The labs then perform a comprehensive set of analyses in accordance with the MAUCRSA and regulatory requirements. Laboratories must provide distributors with certificates of analysis detailing the findings of each analytical test (pass or fail). Before a batch can be issued to retailers, it must pass all necessary testing.

As of October 2019, only 27 licensed cannabis testing laboratories served the whole of California.

What Accreditations Do Marijuana Testing Facilities Need in California?

Per the DCC rules, testing laboratories must:

  • Be ISO accredited
  • Use standard operating procedures
  • Develop a laboratory quality assurance program
  • Participate in a proficiency testing program

To be approved by the ISO, cannabis testing laboratories must obtain and maintain ISO/IEC 17025 accreditation. ISO/IEC 17025 is a quality management system and a standard for evaluating technical competence in laboratory testing and calibration services. It applies to companies that produce testing and calibration results. ISO (International Organization for Standardization) is a not-for-profit organization of more than 160 national standards bodies.

Through the efforts of ISO members, the organization brings together experts to exchange knowledge and develop voluntary, consensus-based, market-relevant international standards that promote innovation and solve global problems. Over 100,000 laboratories worldwide depend on the ISO/IEC 17025 standard as their main source of laboratory certification, according to ISO.

ISO/IEC 17025 certification certifies that a laboratory follows a sound quality management system and can deliver testing and calibration results. Accredited labs perform tests in line with internationally recognized standards (ISO/IEC 17025), and the findings are approved by a wide variety of governmental and regulatory bodies. The agreement between accrediting organizations mandates accredited members' test results to meet the same minimum quality standards independently of the accreditation body, and that calibration results will be treated as if performed by the accredited member.

In order to obtain ISO/IEC 17025 accreditation, a laboratory's quality management system and technical capability will be assessed by an appropriate "third-party" accrediting body. Audits will also be conducted regularly to verify that the accreditation is maintained. Only a recognized accrediting body may provide an ISO/IEC 17025 accreditation.

Some of the factors taken into consideration before an ISO/IEC 17025 accreditation is issued are:

  • The staff's credentials, training, and experience
  • Adequate quality assurance procedures
  • Sampling techniques
  • Testing procedures
  • Test validation methods
  • Traceability of measurements to national standards
  • Procedures for accurate recording and reporting
  • Testing facilities

Following the latest update to the ISO/IEC 17025 standards in 2017, there are now five standard requirements for an ISO/IEC 17025 accreditation.

How Much Does a Marijuana Testing Laboratory License Cost in California?

California law mandates that cannabis licensing fees cover the DCC's expenses associated with industry supervision and are tiered such that larger businesses pay more. The application and licensing costs are determined by economists who conducted a study of the state's cannabis sector and proposed cost amounts.

Cannabis testing laboratory license fees are based on the gross annual revenues generated by the laboratories. For a new license applicant, the gross annual revenue is calculated based on the gross sales and revenue expected during the first 12 months after licensure.

License and application fees are:

Gross Annual Revenue Application Fee License Fee
Less than or equal to $160,000 $1,000 $3,000
$160,001 - $320,000 $1,000 $6,000
$320,001 - $480,000 $1,000 $8,000
$480,001 - $800,000 $1,000 $13,000
$800,001 - $1,200,000 $1,000 $20,000
$1,200,001 - $2,000,000 $1,000 $32,000
$2,000,001 - $2,800,000 $1,000 $48,000
$2,800,001 - $4,400,000 $1,000 $72,000
More than $4,400,000 $1,000 $112,000


Cannabis testing laboratory licenses are renewable every year. The license fee corresponding with the licensing tier category identified by a licensee based on the expected gross annual revenue over the next 12-month period will be the renewal fee.

Are there Local Regulations for Cannabis Testing Facilities in California?

Yes. Many California municipalities have ordinances and regulations restricting or guiding the operations of cannabis testing facilities in their jurisdictions. These ordinances include guidelines on air quality, odor control, chemical exposure, and ventilation requirements and standards.

Ordinances are regulations established by cities and counties to set even more specific rules for the local community. An ordinance is only effective in the city or county in which it was enacted. Contact your municipal and county governments to see if they have enacted any ordinances pertaining to cannabis testing laboratories.

Cannabis testing laboratory ordinances are available in the City of Lake Forest, City of Irvine, and City of California City. Typically, applicants must obtain permits and approvals verifying compliance with zoning provisions, building codes, and fire safety procedures.
