Cornerstone Collective is California’s first research-based medical cannabis collective, established in 2007 under California’s Compassionate Use Act.

We are a non-profit collective whose focus is on cannabis therapeutics and the wide variety of its medicinal applications. Our goal is to provide a safe, responsible, and welcoming environment for our patient community. Drawing on over 9 years of practice we offer personalized service aimed at effectively treating specific conditions. We employ strict testing standards to ensure the purity and quality of our medical grade products.

Making the
Right Choice

Choosing the right cannabis medicine can be difficult.

Since many patients respond differently to cannabis strains, we rely on patient feedback data collected over many years to help them make more informed choices.  The variety of our medical cannabis genetics are unmatched, highly effective, and include several medical Cannabis Cup winners.

Strict
Quality Control

We employ the strictest standards for guaranteeing the highest quality medical cannabis for our patient-members.

Mold, pesticides, fertilizers, and insect damage are the most common contaminants of medical marijuana. In particular, mold poses a dangerous threat to patients, since smoking or vaporizing does not destroy mold toxins. Unfortunately, quality control at many cannabis dispensaries is poor or non-existent. All Cornerstone medical cannabis is tested in a professional laboratory to detect and eliminate contamination. Additionally, we test and provide complete cannabinoid and terpenoid profiles for all of our products.

Cannabis is a perishable product. Therefore, Cornerstone stores all its medicine in a specially designed refrigerator kept at a specific temperature and humidity to preserve its purity and potency. Since naturally occurring solvents in cannabis can interact with many plastics to form carcinogens, we have chosen to only use glass and chemical-resistant polypropylene for the purposes of storing and packaging our medicine.
