Short answer

A small number of cannabis brands sell a patch labeled transdermal in US dispensaries. The two best known are Mary's (Mary's Medicinals) and Papa & Barkley. Both sell through licensed state markets, not nationwide. What you find on the shelf depends on your state's inventory and its dose rules.

Cannabis Transdermal Patch

Transdermal vs topical

A transdermal patch moves cannabinoids through the skin and into the bloodstream. A topical balm or lotion stays in the skin and the tissue under it. That changes onset and duration. Patch onset runs 15 minutes to 1 hour. Effects last 8 to 12 hours on most products. Topicals produce little to no detectable blood THC in most users.

State operators

Multi-state operators list patches in select markets. Trulieve sells patches in Florida. Curaleaf sells patches in several Northeast states. Formulas and doses vary by state because each market writes its own rules. A 10 mg patch in one state can be a 20 mg patch in another.

Dose

Most single patches hold 10 mg THC. Some hold 20 mg or 30 mg. Cutting a patch is not advised. The drug sits in an adhesive matrix that does not divide into equal parts. New THC users should ask the dispensary for the lowest dose on hand. The patch releases for the full wear time, so a high dose lasts hours longer than a vape hit.

Price

Single patches retail from $10 to $30. Multi-packs run $60 to $120. Price tracks THC content and state taxes. Medical patients in some states pay a lower tax rate.

Limits

No cannabis transdermal patch carries FDA approval. The FDA has approved one cannabis-derived drug, CBD-based Epidiolex, and no patch product. Dispensary patches fall under state medical and adult-use programs. Skin redness under the patch is the most common complaint. Rotate placement sites between uses.
