How this site is funded

This site has no ads, no sponsors, and no industry funding. It is built and maintained by one person, and that is intentional — keeping the project independent means the information stays honest.
Hosting, domain costs, research access, and the time it takes to read, verify, and write all cost something. If this site has been useful to you, any contribution helps it continue.

Other ways to help

  • Share a page. If something here was useful, send it to someone who might benefit — a text, an email, a social media post.
  • Suggest a correction. If you find an error, a broken link, or a claim that needs updating, email [email protected].
  • Talk about it. If secondhand cannabis smoke is a problem in your community, say so — to neighbors, to local officials, to school boards.
  • Use the data. Everything on this site is licensed CC BY-NC-ND 4.0 for educational use.

Where the money goes

Every donation goes directly to:
  • Web hosting and domain registration.
  • Research database access.
  • Time spent reading, verifying, and writing.
  • Future development — more data, broader reach.
This site will never run ads, accept industry funding, or charge for access. If you want to know how funds are used, ask at [email protected].
