Alaska’s Department of Health has proposed rule changes that would double the validity period for medical marijuana registry cards, from 12 months to 24, and allow a single caregiver to serve more than one registered patient, according to a report by The Marijuana Herald. The proposal, published September 11, would also drop a requirement that applicants provide Social Security numbers. State officials have opened a public comment period running through November 6, with a telephone hearing set for October 29. The changes remain proposals pending review, and officials said they are not expected to require additional funding.
