Cornerstone Research is California’s first research medical cannabis collective. Our focus is on the science of medical cannabis, from the strict criteria we use to select our medicinal strains to the microscopic inspection of all products for contaminants. We actively solicit members with extensive experience in growing their own medicine and who are willing to furnish excess medicine to other patients for whom growing is not feasible.
