Subject Headings

Certain business databases such as IBISWorld, Mergent Online and Business Source Premier allow you to search by North America Industry Classification System (NAICS). It may be useful to write these codes down as you find them when starting your research to help facilitate your search strategy.​

NAICS is the standard used by Federal statistical agencies to classify business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. It uses a hierarchical structure comprised of main two-digit sector codes and various subsector and industry codes.

Marijuana actually falls under three hierarchies: 

  • 11 - Agriculture, Forestry, Fishing and Hunting
    • 111419  Marijuana, grown under cover
    • 111998  Marijuana, grown in an open field
  • 42 - Wholesale Trade
    • 424590  Marijuana merchant wholesalers
  • 45 - Retail Trade
    • 453998  Marijuana stores, medical or recreational

NAICS is reviewed every five years for potential revisions (the last time was 2022) so that the classification system can keep pace with the changing industry. See the NAICS Update Process Sheet for more information.
