Privacy Policy

We use a single age-verification cookie. No tracking, no data sales, no third-party analytics.

Last verified: April 2026

Our Approach to Privacy

CannaScience.org is an educational site about cannabis science. We believe that visitors seeking information about cannabis — whether for personal health decisions, academic research, clinical practice, or policy understanding — deserve strong privacy protections. Given the ongoing federal prohibition of cannabis and the sensitive nature of health-related information seeking, we have designed this site to collect as little data as technically possible.

What We Collect

Cookies (Two)

We set a single cookie (cannascience_age_verified) when you confirm you are 21 or older. This cookie lasts 30 days and prevents the age gate from appearing on every visit.

We also set a cookie consent acknowledgment cookie (cannascience_cookie_consent) when you dismiss the cookie notice. This lasts one year.

Server Logs

Like all websites, our web server automatically logs basic request information (IP address, page visited, browser type, timestamp). These logs are used solely for security monitoring and technical troubleshooting. They are not analyzed for user behavior, shared with third parties, or used for any purpose beyond site operations.

What We Do Not Do

  • We do not use Google Analytics or any third-party analytics platform
  • We do not use tracking pixels, fingerprinting, or retargeting technologies
  • We do not sell, share, trade, or monetize any visitor data
  • We do not collect email addresses, names, or personally identifiable information
  • We do not serve advertisements of any kind
  • We do not use social media tracking widgets or embed social media content
  • We do not build user profiles or track visitors across sessions

Third-Party Resources

We load the following resources from third-party content delivery networks for site functionality and appearance:

  • Bootstrap CSS/JS from cdn.jsdelivr.net
  • Bootstrap Icons from cdn.jsdelivr.net
  • Google Fonts from fonts.googleapis.com

These services may log standard HTTP request information per their own privacy policies. No user data is transmitted to these services beyond what is inherent in an HTTP request (IP address, browser user-agent, referring page). We chose CDN-hosted assets for performance and reliability.

Data Retention

We do not maintain any user database. Server logs are retained for a limited period for security purposes and then deleted. The age-verification cookie expires after 30 days. The cookie consent cookie expires after one year. No other persistent data is stored about visitors.

Children’s Privacy

CannaScience.org is intended exclusively for adults. While the site contains educational and scientific content rather than cannabis advocacy, our age-verification gate is designed to restrict access to those 21 and older, consistent with legal cannabis age requirements across U.S. jurisdictions. We do not knowingly collect any information from minors.

Changes to This Policy

If we ever change our privacy practices, we will update this page with a new "last verified" date. We have no plans to add tracking, analytics, or advertising.
