The Colorado Department of Public Health is looking to limit the number of patients that private medical marijuana caregivers can serve, as well as put a cap on the number of plants an individual may grow. Currently, caregivers can serve more than five patients by applying for a “medical necessity” waiver from the CDPHE and plant counts can be increased from just six with a doctor’s recommendation, which is often the case with patients who make their own concentrates or edibles.
