Medical patients

What medical status changes

We’re licensed for adult-use and medicinal sales. If you hold a physician’s recommendation or a county medical ID card, three practical things change: your purchase limit, your paperwork and what you pay in tax.

We’re a shop, not a clinic. Nothing on this page is medical advice, and we can’t tell you whether cannabis is right for you or what it might do for a condition. That conversation belongs with a physician. What we can do is explain the paperwork, the limits and the products — which is what this page is for.

Age and purchase limits are set by the Department of Cannabis Control in 4 CCR §15409; a recommendation that specifies a different amount for a patient takes precedence. The sales-tax exemption is Revenue & Taxation Code §6369.6 and requires the MMIC card specifically — a physician’s recommendation on its own doesn’t qualify. The excise tax is never exempt. Adult-use and medicinal limits can’t be combined. Verified 20 September 2026. If you’re 18–20 with a recommendation, call us at (415) 757-0995 before you visit.

The paperwork

A recommendation and a card are not the same thing

People use “medical card” for both, which is where the confusion starts.

Most people have this

A physician’s recommendation

A California-licensed physician can recommend cannabis — they can’t prescribe it, because federal scheduling doesn’t allow a prescription to be written for it. The recommendation is the document.

  • Qualifies you for the higher medicinal purchase limit
  • Qualifies you for our 10% discount
  • Does not exempt you from state sales tax

Worth the trip

The state MMIC card

A Medical Marijuana Identification Card, applied for through your county health department with your recommendation. It’s the only document that removes the sales tax.

  • Everything the recommendation gets you, plus
  • Exempt from state sales and use tax on qualifying purchases
  • Show it with a government photo ID at the counter
  • Excise tax still applies — nobody is exempt from that

If you buy regularly, the MMIC usually pays for itself. We can’t apply for it on your behalf — that’s between you, your physician and San Francisco’s Department of Public Health (which issues the card for San Francisco residents).

Being straight with you

What our staff can and can’t do

What we can do

  • Explain what a product is — its format, its cannabinoid content, how it’s taken and how long a package lasts.
  • Show you the lab results and the label for anything on the shelf.
  • Point you to the lowest-dose version of a format, and to high-CBD, low-THC options.
  • Explain the paperwork, limits and tax — the whole of this page, in person.
  • Take your time.

What we can’t do

  • Tell you what cannabis will do for any health condition. We’re not clinicians and it isn’t legal for us to say so.
  • Recommend a dose, or tell you how a product will interact with medication you’re taking.
  • Issue a recommendation or a card, or refer you to a particular physician.
  • Sell to you without valid, unexpired ID — every visit, no exceptions.

If a shop tells you a jar will fix your back, walk out. They don’t know, and they’re not allowed to say it.

On the shelf

Formats people ask about

Described by what they are and how they’re taken. What they’re right for is a conversation for you and your physician.

Tinctures & capsules

Liquid in a dropper bottle, or a measured capsule. Both are marked in milligrams per dose, so the amount is a number rather than a guess.

Under the tongue · Swallowed

Topicals

Balms, lotions and patches applied to the skin. Most are formulated not to be intoxicating — the label tells you.

Applied to skin

Edibles

Gummies, chocolate and drinks, marked in milligrams per piece and per pack. Onset is slow — typically 30 to 90 minutes.

Eaten · Start low

CBD

High-CBD, low-THC

Products with a high CBD to THC ratio, found across most categories. Ask and we’ll pull what’s in stock — the ratio is printed on every package.

Across all formats

Medicinal questions

The ones we actually get

Do I need a medical card to shop here?

No. We’re licensed for adult-use as well, so anyone 21 or over can shop with a government photo ID and nothing else.

Can I buy here if I’m 18?

Yes, with a valid physician’s recommendation or a state MMIC card, plus your photo ID. California allows licensed medicinal retailers to serve patients from 18. Without that documentation the minimum is 21.

Does a medical card save me money?

Two ways. Our 10% medical discount applies with either a recommendation or a card.

The state sales and use tax exemption needs the MMIC card specifically — a recommendation on its own doesn’t qualify. Bring the card and a government photo ID. The cannabis excise tax still applies either way.

How do I get an MMIC card?

Through your county health department — in San Francisco, the Department of Public Health — using a physician’s recommendation. There’s a county fee and it’s renewed annually.

We can’t issue one or apply on your behalf, and we don’t refer to particular physicians.

Why do doctors “recommend” rather than prescribe?

Because cannabis remains federally scheduled, so a physician can’t write a conventional prescription for it. California law uses recommendation instead — it’s the legally operative term, and it’s why you won’t collect cannabis from a pharmacy.

Can staff tell me what to take for a condition?

No, and you should be wary of anywhere that does. Our staff can explain what a product is, what’s in it, how it’s taken and what the lab report says. Whether it suits your situation is a question for your physician.

Bring the card, we’ll do the rest

Open every day 8am–10pm at 3109 Fillmore St. Shop in store or order ahead for pickup — the discount applies to both.

Are you 21 or older?

You must be 21 or older to enter, or 18 or older with a valid medical recommendation.
