Six rules, and where each one lives in the build.
Each of these is cited to the statute or regulation it comes from. Rules change, and this list is checked at every quarterly audit.
01 Age affirmation before the site talks to anyone
California requires a method of age affirmation before any direct, individualized communication a licensee controls. We build the gate to render before the first paint, keep keyboard and screen-reader users inside it, remember the answer, and cover the chat agent and SMS opt-in too, not just the front door.
Bus. & Prof. Code 26151(c)
02 Your license number on every page that markets
All advertising and marketing must legibly identify the licensee by license number. A website is marketing. We put the number in the site footer and on every menu, promotion, and landing page, and check it again whenever the license renews.
Bus. & Prof. Code 26151(a)
03 The 71.6 percent rule for anything you place
Digital advertising may only run where at least 71.6 percent of the audience is reasonably expected to be 21 or older, backed by audience data. We do not run ads, and Google and Meta largely refuse cannabis ads anyway, so the site and search are the channel. We build the site so it earns the traffic instead.
Bus. & Prof. Code 26151(b)
04 No free product, no giveaways, nothing that appeals to kids
State regulations bar advertising free cannabis goods, buy-one-get-one offers, contests and raffles, and any image or word that appeals to children, including cartoons and candy language. We write and review promotion copy against that list before it goes up.
4 CCR 15040
05 Prop 65 warnings where the purchase happens
For online sales the warning, or a clearly marked WARNING link, has to sit on the product page before checkout, not buried in a footer. Cannabis smoke and delta-9 THC are on the list. We wire the warning into the product template so every new product carries it.
27 CCR 25602
06 Delivery zones that match the jurisdictions
Licensed delivery can reach across the state, but cities can restrict it, and your license sets where you may operate. We build the address check to say yes or no by jurisdiction, so the site never promises a delivery you cannot legally make.
