Founded December 2015

before you read about us, note our offer for dosist/hmbldt vape pens:

We still have hmbdlt pens in stock: Arouse, Passion, Relief, Calm, and Sleep, and mini dose pens as well, including Bliss.  Have a look and text or call for info?  Buy four 200 dose pens, get a mini (50 dose) pen as a gift.  Let us know your needs? :)



Update June 19, 2018

We are open until early July, deliveries by appointment.

Please note we continue to seek partners in order to procure medication for our Members, but it is increasingly likely we will close definitively in July. 


We still have inventory, all items on the menu are available, in some cases in limited quantities.  Please text or call and let us know your needs ?


For info, Marin County and San Rafael are the only localities in Marin to authorize cannabis businesses.  The County has started the process for permit applications and we are too small to finance the new requirements, which basically require significant capital investment, and therefore favors corporate entities over artisan businesses, the latter being the model for MMC.


The idea of MMC was to provide service and not just product.  Jeff delivered over 2,000 Members himself to keep costs down and to be sure he pretty much had met every Member. 

We are grandfathered to operate until the end of the year, and are actively seeking a dispensary-partner from outside the County, interested in serving our 1,650 Member collective.

Even if MMC shuts down in early July, we will continue to seek a solution for our Members.

Meanwhile, items still shown on the website are available to Members in some cases in limited quantities.  In all cases, deliveries are by appointment, please text or call Jeff at 415-202-4085.


Thank you to all of the Members of the MMC Collective, you have made this a very positive experience, I have learned much from our exchange, and I have made many new friends.  I wish all of you the best in however the future evolves, and I welcome all of you to remain in touch.  Let's keep the dialogue, and find solutions together.



For info, MEMBERS please call Jeff on 415-202-4085
telephones open 10am - 5pm, delivery by appointment within 24h

We are very grateful to our Members and extend our sincere thanks for your understanding.  We will communicate with Members as we have updates.


We still have hmbdlt pens in stock: Arouse, Passion, Relief, Calm, and Sleep, and mini dose pens as well, including Bliss.  Have a look and text or call for info?  Buy four 200 dose pens, get a mini (50 dose) pen as a gift? :)

Update on March 22, 2018

Please note that since January 1, 2018, we are experiencing disruptions in our supply chain due to licensing issues for our suppliers and for us.  In the interim, we are doing our best to see that the website remains up-to-date and only lists products that are in stock, but please be aware that some products remain on the site but available only in limited quantities.

We note that we do have the full range of hmbldt (or dosist) vape pens available in the 200 dose size, including Bliss, Arouse, Passion, Relief, Calm and Sleep.

We also have the full line of Care by Design vape cartridges, which combine CBD and THC, and available in the following ratios of CBD:THC -- 18:1, 8:1, 4:1, 2:1, and 1:1.

Members, please feel free to contact us for more information.  Also, if you might be interested in collaborating on a Marin-based cannabis business incubator, please contact Jeff.

Have a blessed start to your Spring and our best wishes for your wellness.


UPDATE January 1,  2018

The new law in California segments the Cannabis business into several different categories.  For the purposes of the law, Marin Medicinal Cannabis (MMC) is a mutual benefit corporation and a nonprofit, formed under California law in December 2015 for the purposes of providing medical marijuana to members of its collective.  Please note that we remain a Medicinal Cannabis provider formed under the old law, and grandfathered which means able to conduct business until the end of 2018.  By the end of 2018 we have to obtain a state and local license or cease activity.  

We remain a medical marijuana collective and therefore you must have a valid medical recommendation and join our Collective in order to obtain medication.  

The new law governing cannabis businesses in California obliges us to announce the following changes:
1) in addition to California Sales Tax of 9.5%, we have to charge the new California Cannabis Excise tax, which is 15%.  This means all products are now taxed at a total rate of 24.5%,
2) we are no longer allowed to gift any articles
3) no samples are allowed (private tastings are permitted, but cannabis events require a Fairgrounds)
4) the daily limit for purchases is 8 oz/day for medical (it is 1 oz/day for Adult use)
5) all edibles must be divisible into maximum doses of 10mg THC (we will provide instructions explaining how to divide certain edibles for this purpose)


Thank you for your understanding, and for more information please consider these links:



We will update this website as additional information becomes available.


We are happy to discuss your needs, preferences, and experience.  We will attempt to help you identify the most appropriate cannabis products for your needs, and we can recommend products that are not psychoactive.

Also, if you need advice on getting a medical recommendation, please let us know.





We really believe in medicinal cannabis, and our pure products provide the best means for medicating with this amazing plant.  Also, watch my blog, I am attempting to track down some of the science, and provide links to medical studies and articles that I think clarify what we are doing.

In addition to products up to 100% CBD or THC, we have specialized in offering non-psychoactive CBD products, with topical remedies that utilize THC, but are not psychoactive.

We recommend new members place first orders via the online store. Please do not hesitate to call us for guidance while viewing the online store. Note that you do not have to pay to submit your order/without pay. Payment is upon delivery, and only accept cash. 

We specialize in California's finest medicinal cannabis products.  Our criteria is high purity -- when possible, pharmaceutical grade, as is the case for Care by Design and Absolute Xtracts' products.  We do our best to only offer the best of what we find in the market, while trying to be sure to address all possible formats:  flower, vape, edibles, topicals, dabables, etc.

We are also following the evolution of the market, seeking purity first, but then innovation.  Lately, what we are seeing is an increased focus on blending cannabis with herbs, with the intention of creating a specific remedy or mood-enhancer.  As one very recent example, HMBLDT dose pens, a completely newly thought-out vape device that provides 200 exact doses, available in BLISS, [PASSION, AROUSE -out of stock] , RELIEF, CALM and SLEEP.  Another great example is the Whoopi & Maya line of products (Whoopi Goldberg), which include RUB, SOAK, SAVOR, and RELAX.

As for innovations, the above all count, but so do super-pure products, such as our distillates, where our offering includes products by Old Timer.  This is extracted cannabis that is then triple-fractionally distilled.  This creates a very pure (over 90%), highly potent, highly flavorful distillate that can be dabbed, added to a joint or bowl.  These distillates all offer distilled terpenes, as well, with exception flavor profiles.

I really enjoy innovation, but only so long as it is accompanied with an eye on purity and quality, which is not the case for many products.  We reject approximately 20 products for every supplier we accept.

Our product offering reflects a selection based on strict criteria.  We only work with suppliers that stand behind their products, are intending to be licensed and permitted so they are around next year and thereafter, and ones that offer purity and quality.  And yes, we only offer products we test, and would use regularly.  Please note, we do occasionally discontinue suppliers for lack of quality, but our goal is to provide only products that, if they work for you, we can be sure to provide to you for years to come.


We also post closings and up-to-date hours on Yelp:  Yelp: Marin-Medicinal-Cannabis
and yes, free edibles for Yelp reviews, just call and let us know :)

Best wishes for your wellness.

About Our Collective


“I slept and dreamt that life was joy. I awoke and saw that life was service. I acted and behold, service was joy.”  - Rabindranath Tagore


My name is Jeffrey Grava and I am blessed and grateful today that I started this collective at the end of 2015.  My idea then was to provide a high level of service, meaning not just monitoring the phones and text messages, but providing product selectivity, product knowledge, and sharing experiences.  My model is that of owner-operator, and for the most part I am responsible for all of the interface with both Members and Suppliers.  I strive to bring you the best products in California, and only the best, accompanied by the best service I can muster, for all of Marin County.

I really like the idea of a Collective, and am here to see that we offer the medicine and the service our Members need.  I am always open to feedback, positive or negative!

I want to be your trusted, reliable, and friendly source for your medical marijuana needs.  I like to help solve issues and understand conditions, and where I can or where another Member had success, I will try to offer frank advice.  I will always explain as much as possible what this plant can or might do, and won't or can't do.  I will always remind you that everyone is different, and every individual's endocannabanoid system is different as well.  This means that each person will assimilate cannabis a little differently, and it is important that we discuss and look for your own specificities. 


We invite our members to think of MMC as your collective, and feel free to call or email comments on our service and offering.  For more information see "Our Story" or give us a call:
