What Every Label Must Include
OCM regulations require all cannabis product labels to display:
- THC and CBD content — both total and per serving, expressed in milligrams and percentages
- Product weight or volume — the net amount of cannabis in the package
- Metrc tracking number — the seed-to-sale tracking identifier (Metrc launched December 2025, replacing the previous BioTrack system)
- Lab testing results — confirmation that the product passed all required safety tests
- Batch or lot number — for traceability in case of recalls
- Cultivator/processor identification — who grew and/or manufactured the product
- Expiration or packaging date
- Warning statements — including "For use by adults 21+ only" and health warnings
Understanding THC Percentages
THC content is displayed differently depending on the product:
- Flower: Listed as a percentage (e.g., 22% THC). This represents the proportion of THC by weight in the dried flower.
- Edibles: Listed in milligrams per serving and per package (e.g., 10mg per gummy, 100mg per package).
- Concentrates: Listed as a percentage, typically 60-90% THC.
- Tinctures: Listed in milligrams per milliliter and per bottle.
The Metrc Tracking System
New York launched the Metrc seed-to-sale tracking system in December 2025, replacing the failed BioTrack implementation. Every legal cannabis product carries a Metrc tag that tracks it from cultivation through processing, testing, distribution, and retail sale. This system ensures product accountability and consumer safety.
What Lab Testing Covers
All cannabis products sold in New York dispensaries must pass testing for:
- Potency (THC, CBD, and other cannabinoid levels)
- Pesticides and herbicides
- Heavy metals (lead, arsenic, cadmium, mercury)
- Microbial contaminants (mold, bacteria, E. coli)
- Residual solvents (for extracted products)
- Mycotoxins
This testing is one of the key advantages of purchasing from a licensed dispensary. Unlicensed products carry none of these safety guarantees.
