Usually not by itself, if your sentence is complete. California’s cannabis licensing law says a completed-sentence conviction for possession, possession for sale, sale, manufacture, transportation, or cultivation of a controlled substance is not treated as substantially related to a state cannabis license and cannot be the only reason an application is denied. Two kinds of drug felonies are exceptions, and the rest of your record still matters.

The general rule for completed drug convictions

Business and Professions Code section 26057(b)(5) addresses this directly. Except for the two categories described below, a prior conviction for possession, possession for sale, sale, manufacture, transportation, or cultivation of a controlled substance, where the sentence, including any probation, incarceration, or supervised release, has been completed, “is not considered substantially related, and shall not be the sole ground for denial of a license.” The Department of Cannabis Control’s regulation, California Code of Regulations, title 4, section 15017(d), repeats the rule.

The completed-sentence condition matters. Until every part of the sentence, including any probation, incarceration, or supervised release, is finished, this protection does not apply to that conviction.

A conviction that comes after you are licensed is treated differently: under section 26057(b)(5), a conviction for any controlled substance felony after licensure is grounds for revoking the license or denying its renewal.

Convictions that can still count

Section 26057(b)(4) lets the department deny an application when the applicant has been convicted of an offense substantially related to the business, and it lists offenses that are included. Two are drug felonies that fall outside the general rule:

  • A felony conviction that involved a minor in drug activity: hiring, employing, or using a minor in drug transport, sales, or distribution, or selling, furnishing, administering, or giving a controlled substance to a minor (or offering to sell or furnish one).
  • A felony drug-trafficking conviction with an enhancement under Health and Safety Code section 11370.4 or 11379.8.

The drug rule also covers only the drug conviction. The same list includes a violent felony, a serious felony, and a felony involving fraud, deceit, or embezzlement, so other convictions on your record can still be weighed.

A conviction that counts is not automatically the end

Conviction-based denial is discretionary. Section 26057(b) says the department “may deny” an application on these grounds; the mandatory “shall deny” in section 26057(a) applies when the applicant or the premises does not qualify for licensure under the cannabis law. If the department finds you otherwise suitable and that granting the license would not compromise public safety, section 26057(b)(4) requires “a thorough review of the nature of the crime, conviction, circumstances, and evidence of rehabilitation.”

Two further protections apply. First, Business and Professions Code section 26059 says an applicant cannot be denied a license if the denial rests solely on “a conviction that was subsequently dismissed pursuant to Section 1203.4, 1203.4a, or 1203.41 of the Penal Code,” or under any other provision allowing dismissal of a conviction, or on a substantially related conviction for which the applicant has a certificate of rehabilitation. Second, section 15017(e) lists rehabilitation criteria the department must consider when deciding whether an applicant with a substantially related conviction should be licensed, including the nature and gravity of the offense, your record as a whole, the time that has passed, compliance with probation, parole, restitution, or other sanctions, and evidence of a dismissal, pardon, or certificate of rehabilitation. One criterion is specific to cannabis: whether the person has “a felony conviction based on possession or use of cannabis or cannabis products that would not be a felony” if the person were convicted of it on the date of the application.

If your application is denied

Under Business and Professions Code section 26058, the department must notify you of a denial in writing. You then have 30 days from service of that notice to file a written petition, and the department must set a timely petition for a hearing under the Government Code’s administrative hearing procedure.

Getting your application ready

  • Gather proof that any sentence, including probation or supervised release, has been fully completed.
  • Pull paperwork on any dismissal, such as relief under Penal Code section 1203.4, and any certificate of rehabilitation or pardon.
  • Be ready to address the rehabilitation criteria directly: time elapsed, compliance with your sentence, and your record as a whole.
  • If your conviction was a cannabis possession or use felony that would not be a felony today, say so and document it.
  • Be accurate about your criminal history on the application; do not omit or misstate a conviction.

These rules govern the Department of Cannabis Control’s state license. Local rules are separate: Business and Professions Code section 26200(a)(1) preserves a city or county’s authority to adopt and enforce its own ordinances regulating licensed cannabis businesses, including local business license requirements, or to prohibit one or more types of cannabis businesses entirely, so check local requirements separately.
