SPARC is a nonprofit collective dedicated to providing lab-tested, affordable, high quality cannabis and subsidized health services to our members. We aim to educate our patients about cannabis
treatments and other alternative health approaches to supplement their medicine. SPARC advocates for government change. We seek to be a voice for the implementation of best practices for the
regulation and taxation of medical cannabis. Download a press kit here.


Serving patients since 2001…SPARC began as a collaboration between several small collectives serving distinct patient populations in San Francisco. SPARC’s work was focused primarily on
serving low-income patients suffering from chronic and terminal illnesses. As our member-base continued to expand through the integration of small patient collectives, we sought a permit from
the City of San Francisco to open a central healing center and dispensary. This important step allows us to increase our capacity to serve a wider array of members. Our organization is rooted in the
same compassionate, patient-centered service that we have maintained for almost a decade. We work to bring a community-friendly and scientific approach to providing medical cannabis to our
members. Your membership with SPARC helps us continue to expand our free health service programs, as well as our subsidized distribution network for seriously ill, low-income patients in San
Francisco. We have been providing medical cannabis to critically ill patients in hospice at no cost for almost 10 years.

“We are grateful for SPARC’s partnership and support. We have seen many patients whose conditions have greatly improved through
the use of cannabis for pain management, nausea, harm reduction and other valuable medical uses.”
– Tim Patriarca, Former Executive Director of Maitri AIDS Hospice.


SPARC cultivates the vast majority of its own medicine with the expert member-cultivators on staff. Our team uses sustainable growing techniques to bring out the best qualities of the plant. We
oversee the production of most of our medicine from seed to harvest to packaging. Our aim is to provide consistent high-grade cannabis our members can rely on. We focus on bringing out the
highest medicinal qualities of each strain that we offer. We constantly work to increase our knowledge of new cultivation techniques and innovations, and we work with our members to ensure this
knowledge finds its way into higher quality medicine. Because we oversee much of our own production, we can offer more affordable prices to our patients on select top-shelf medical cannabis.


SPARC is one of the few dispensaries in California to have its medicine tested to ensure safety and quality. It is vitally important to ensure that there is no trace of mold, pathogens or pesticides in any cannabis
that is provided for patient members. Quality is usually determined by the amount of symptom relief that a medicine provides and the reliability of the medicine to produce the desired effect. Not
only do we measure the amount of THC in each strain we offer, but using standard analytical techniques, we can assay for the presence of other therapeutically significant cannabinoids such as
cannabidiol (CBD). Our packaging lists the percentage of THC, CBD, and CBN concentrations for each strain, allowing our members to select the right medicine for their health needs. Our long-term
aim is to develop a more scientific approach that includes the possibility of documenting and researching which plant variations and horticultural practices can be combined to maximize the
healing qualities of specific strains.
