Because you're searching for the wrong thing! Emerald can grow marijuana and profit from it... indirectly by establishing itself through collectives and coops as a "designated primary caregiver" service, Under SB 420 (Medical Marijuana Program, MMP)
A primary caregiver can cultivate and possess as much marijuana as a physician recommends to meet the needs of their patients.

You see how the quotations end after caregiver???? THEN STOP SEARCHING FOR "Primary caregiver ??SERVICE??" No... it's just primary caregiver. Get your facts straight.
