What This Study Found

Among 501,012 consumable product listings, multisystem routes of administration were most common (41%), followed by respiratory (37%) and digestive (20%). THC was the dominant compound (63.3%), and 42% of listings featured at least one flavor, with lemon, cake, and strawberry topping the list.

Key Numbers

501,012 consumable listings analyzed; 41% multisystem ROA; 37% respiratory; 20% digestive; 42% featured flavors; top flavors: lemon (8.9%), cake (7.9%), strawberry (5.6%); THC was 63.3% of compound types

How They Did This

Researchers scraped 573,854 unique US product listings from the Weedmaps e-commerce platform between September and November 2023, removing non-consumable items and coding the remainder for product characteristics, routes of administration, and flavors.

Why This Research Matters

As cannabis markets mature under legalization, the sheer variety and flavor-forward marketing of products raises questions about consumer appeal, youth attraction, and regulatory oversight that parallel concerns seen with flavored tobacco and vaping products.

The Bigger Picture

This is one of the first large-scale snapshots of what the legal cannabis marketplace actually looks like at the product level. The dominance of flavored products and the wide variety of delivery methods reflect a rapidly diversifying industry that regulators are still catching up to.

What This Study Doesn't Tell Us

Data came from a single e-commerce platform (Weedmaps) and may not represent all cannabis sales. Product descriptions were self-reported by dispensaries. The study did not assess potency or verify product contents.

Questions This Raises

  • ?How do flavored cannabis products influence youth initiation compared to unflavored options?
  • ?Do different routes of administration carry different health risk profiles?
