SPARC is one of San Francisco’s pioneer cannabis brands, dating back to 1998 when CA Proposition 215 passed, making medicinal cannabis available to patients with a doctor’s recommendation. The first SPARC retail facility opened in 2010 in the SOMA neighborhood of San Francisco. Two commercial-scale cultivation facilities in SF followed, as well as four more dispensaries and a Biodynamic farm in Sonoma County’s lush wine country.
