Cannabis is legal for adults 21 and older in San Diego under California law, sold through state-licensed retailers, and visitors can buy with an out-of-state or foreign identification. It remains prohibited under federal law — which is why crossing the border with it, or using it as a service member, carries consequences state law does not soften.
Why this site exists
Most cannabis information about San Diego is published by businesses that want to sell you something. That shapes what gets written and, more importantly, what gets left out. The rules that would inconvenience a sale — that you probably cannot consume it where you are staying, that the border rule is absolute, that being stationed here changes nothing for a service member — tend to be the rules that go missing.
This site is published by BizRnR, a San Diego software company. We are not a cannabis licensee and we do not sell cannabis. Every legal statement here traces to a public source, listed on the about page — and anything commercial is clearly labelled as such.
