The sale of synthetic marijuana in California is a misdemeanor under California Health and Safety Code § 11357.5. A conviction can result in up to six months in county jail, a fine of up to $1,000, or both. The law also prohibits offering to sell, distributing, furnishing, advertising through labeling or marketing, and possessing covered synthetic cannabinoid compounds or derivatives for sale.
Understanding what qualifies as synthetic marijuana, which activities are prohibited, and what penalties apply can help individuals facing criminal allegations understand their legal rights and options.
What Is California Health and Safety Code § 11357.5?
California Health and Safety Code § 11357.5 prohibits specific activities involving synthetic cannabinoid compounds and their derivatives.
Under subdivision (a), it is illegal to:
- Sell synthetic cannabinoid compounds or derivatives.
- Dispense or distribute covered substances.
- Furnish, administer, or give them to another person.
- Advertise them through labeling or marketing.
- Offer to sell, dispense, distribute, furnish, administer, or give them to another person.
- Possess covered synthetic cannabinoids for sale.
Importantly, a completed sale is not required for every violation. Offering to sell or engaging in other prohibited conduct may be sufficient to support a criminal charge.
For example, a person who offers prohibited synthetic cannabinoid products to a potential customer may face criminal charges even if the customer never completes the purchase.
What Is Considered Synthetic Marijuana Under California Law?
Synthetic marijuana generally refers to substances designed to mimic some effects of natural cannabis by interacting with cannabinoid receptors in the body.
These products are commonly marketed under names such as:
- Spice
- K2
- Synthetic weed
- Fake marijuana
- Herbal incense
- Synthetic cannabis
However, a product’s name or packaging does not determine whether it is illegal. Its chemical composition and the statutory definition are what matter.
Are Spice and K2 Illegal in California?
Spice and K2 products may be illegal when they contain synthetic cannabinoid compounds or derivatives covered by California law.
Labels such as herbal incense or not for human consumption do not automatically make these products legal.
Authorities may examine laboratory testing, product ingredients, packaging, sales records, and other evidence to determine whether a product falls within the statute.
Does California Law Cover CBD-Derived Synthetic Cannabinoids?
Yes. Certain chemically converted cannabinoids can fall within California’s synthetic cannabinoid definition.
Effective January 1, 2026, Assembly Bill 8 expanded the definition under Business and Professions Code § 26001(bf). It includes certain cannabinoids and cannabinoid-like compounds produced through chemical synthesis, reaction, modification, conversion, biosynthesis, or bioconversion.
The definition specifically includes certain forms of THC produced through the conversion of CBD.
However, not every hemp-derived or naturally occurring cannabinoid is automatically classified as synthetic. The substance’s composition, production method, and applicable statutory exclusions must be considered.
What Activities Are Prohibited Under § 11357.5?
California law prohibits several activities involving covered synthetic cannabinoid compounds and derivatives.
1. Selling Synthetic Marijuana
Selling a prohibited synthetic cannabinoid to another person is a misdemeanor under § 11357.5(a).
For example, a convenience store employee who sells a package containing a prohibited synthetic cannabinoid may face criminal charges if the prosecution establishes the required elements.
2. Distributing or Furnishing Synthetic Cannabinoids
A person does not have to receive money to violate the distribution provisions.
Giving or distributing covered synthetic cannabinoids to another person may also be illegal.
For example, distributing synthetic marijuana products to several individuals without charging them may still constitute prohibited conduct.
3. Advertising Synthetic Marijuana
The statute expressly prohibits advertising covered synthetic cannabinoids through labeling or marketing.
For example, a business that promotes products containing prohibited synthetic cannabinoids through product packaging or marketing materials may face potential criminal liability.
4. Offering to Sell Synthetic Marijuana
Offering to sell prohibited synthetic cannabinoids is also prohibited.
A completed transaction is not necessarily required.
For example, a person who offers synthetic marijuana products to a potential customer may face charges even if the customer declines to purchase them.
5. Possessing Synthetic Marijuana for Sale
Possessing covered synthetic cannabinoids with the intention of selling them is a misdemeanor.
Evidence that may be relevant to a possession-for-sale allegation includes:
- The quantity of the substance.
- Individual product packaging.
- Sales records.
- Transaction-related communications.
- Other evidence suggesting distribution or commercial activity.
Possession alone does not automatically establish an intent to sell. The prosecution must establish the required connection between possession and the alleged sale.
What Are the Penalties for Selling Synthetic Marijuana in California?
Selling, distributing, furnishing, advertising, offering to sell, or possessing covered synthetic cannabinoids for sale is a misdemeanor under Health and Safety Code § 11357.5(a).
The maximum penalties include:
| Penalty | Maximum |
|---|---|
| County jail | Six months |
| Criminal fine | $1,000 |
| Combined punishment | Jail time and a fine |
The court may impose jail time, a fine, or both.
The actual sentence depends on the circumstances, available evidence, criminal history, and applicable sentencing rules.
Can Selling Synthetic Marijuana Result in Jail Time?
Yes. A conviction under § 11357.5(a) can result in up to six months in county jail.
However, the maximum sentence is not automatically imposed in every case. The court considers the circumstances and applicable sentencing requirements.
Can a Person Face Both Jail Time and a Fine?
Yes. California law allows the court to impose both imprisonment and a criminal fine.
A conviction may also affect employment opportunities, professional licensing, and business operations. Immigration consequences may also arise depending on the individual’s circumstances and applicable federal law.
Is Possessing Synthetic Marijuana Also Illegal in California?
Yes. Health and Safety Code § 11357.5(b) separately prohibits using or possessing covered synthetic cannabinoid compounds or derivatives.
The penalties depend on the number of prior offenses.
| Offense | Classification | Maximum penalty |
|---|---|---|
| First offense | Infraction | $250 fine |
| Second offense | Infraction or misdemeanor | $250 fine, or up to six months in county jail and/or $500 fine |
| Third or subsequent offense | Misdemeanor | Up to six months in county jail and/or $1,000 fine |
What Is the Difference Between Personal Possession and Possession for Sale?
Personal possession involves possessing a prohibited substance for personal use.
Possession for sale involves possessing the substance with the intention of selling or distributing it.
For example, a person carrying a prohibited synthetic cannabinoid for personal use may face a possession charge. Someone storing multiple packaged units alongside sales records may face a possession-for-sale allegation.
The quantity alone does not automatically establish an intent to sell. The prosecution must prove the applicable elements.
What Defenses May Apply to a Synthetic Marijuana Sales Charge?
A person accused of selling synthetic marijuana may have several potential legal defenses. The appropriate defense depends on the facts, evidence, and circumstances of the case.
1. The Substance Is Not Covered by the Statute
The prosecution must establish that the substance falls within the statutory definition of a prohibited synthetic cannabinoid.
Laboratory testing and chemical analysis may be important in determining whether the substance is actually covered by § 11357.5.
If the substance does not meet the legal definition, this may undermine the prosecution’s case.
2. Lack of Intent to Sell
Possession for sale requires evidence connecting possession to an intended sale.
For example, possessing a synthetic cannabinoid product does not automatically prove that the person intended to distribute it commercially.
The prosecution must establish the required intent through the available evidence.
3. Mistaken Identity or Lack of Involvement
A person may be incorrectly identified as participating in a prohibited transaction.
For example, an employee may be investigated because synthetic cannabinoid products were discovered at a business, despite having no involvement in selling or distributing them.
The person’s actual conduct and involvement matter.
4. Unlawful Search or Seizure
The Fourth Amendment protects individuals against unreasonable searches and seizures.
A defense attorney may examine whether law enforcement officers had a valid warrant, followed its requirements, or relied on a legally recognized exception.
If evidence was obtained unlawfully, the defense may have grounds to request its exclusion.
5. Insufficient Evidence
The prosecution must prove every required element beyond a reasonable doubt.
If the evidence does not establish that the defendant engaged in prohibited conduct involving a substance covered by the statute, the prosecution may be unable to meet its burden.
What Happens After an Arrest for Selling Synthetic Marijuana?
A person arrested or investigated for selling synthetic marijuana may go through several stages of the criminal justice process.
- Investigation: Law enforcement collects suspected synthetic cannabinoid products, reviews records, and interviews witnesses.
- Arrest or citation: Depending on the circumstances, the individual may be arrested or cited.
- Filing of charges: Prosecutors review the evidence and determine whether to file criminal charges.
- Arraignment: The defendant appears in court and enters a plea.
- Pretrial proceedings: The defense and prosecution address evidence, legal motions, and possible negotiations.
- Case resolution: The case may end through dismissal, a negotiated resolution, or trial.
The specific process depends on the charges and circumstances.
Why Should You Speak With a Criminal Defense Attorney?
An attorney can review the allegations, examine laboratory results, assess the legality of searches, and identify potential defenses.
Early legal representation can also help protect your rights and ensure that important evidence and legal issues are properly evaluated.
Can a Business Owner Be Charged for Selling Synthetic Marijuana?
Yes. Business owners and individuals involved in retail operations may face criminal liability if their conduct violates § 11357.5.
Businesses that may encounter these allegations include:
- Smoke shops.
- Vape stores.
- Convenience stores.
- Specialty retailers.
- Manufacturers.
- Distributors.
For example, imagine a California smoke shop sells products containing a synthetic cannabinoid covered by § 11357.5. If evidence establishes that the owner personally participated in prohibited sales or distribution, the owner may face criminal charges.
However, simply owning a business where prohibited products are discovered does not automatically establish criminal guilt. The individual’s conduct and the evidence must be evaluated.
