Cannabis law in Hawaii (2026)

Last reviewed: 9 October 2026

In short: Hawaii has a medical cannabis registry and licensed dispensary programme for certified patients. The Department of Health lists possession of one ounce or more of cannabis as a misdemeanour. Rules for smaller amounts, growing, sale and public use were not confirmed from a readable official statute text.

Notes

  • This is the Department of Health's own summary of HRS chapter 712, which it tells readers to check against the statute. The statute text (capitol.hawaii.gov) could not be read from this server, so thresholds for smaller amounts were not confirmed.
  • Registration is through the Department of Health. The Department's page lists routes for out-of-state patients, but the details were not clearly readable.
