Editorial reviews Free to read Visit Cannigma ↗

Cannigma fields genuine scientific credentials and a credentialed advisory board, but its affiliate and advertising revenue streams are not disclosed near the product rankings where they matter most, making it impossible for readers to assess whether commercial relationships shaped any given recommendation.

What it's really for Science-framed cannabis content hub that earns through affiliate commerce and advertising while building authority via credentialed expert reviewers.

What our grade covers The grade on this page is about Cannabis strains, CBD/THC consumer products, and cannabis accessories reviewed by staff editors with advisory board medical oversight., not everything the site does.

Medium Scoring Confidence Mostly sourced, but a detail or two still needs a primary source, so the grade could shift slightly.

Follow the money

Cannigma's homepage lists affiliate product links, an e-commerce shop, advertising opportunities, medical-card referral services, and paid educational certificates as revenue streams. No dedicated affiliate-disclosure page was found at common URLs (cannigma.com/affiliate-disclosure returned 404), and no disclosure was visible adjacent to product rankings on the strains directory page.

What it costs you
Free to read The reviews are free to read.
How they make money
Affiliate commissions on product links, display advertising, a direct merchandise shop, medical-card referral fees, and paid educational programs.
What they do
Publishes science-anchored cannabis education, strain profiles, and product recommendations. A credentialed advisory board (PharmD, MD, plant scientists) reviews medical content. Staff produce "Best Picks" product roundups alongside strain directories with THC/CBD data and terpene profiles.
What to watch for
Does not disclose a specific affiliate relationship or commission structure adjacent to its product rankings. No published scoring rubric or testing protocol is visible on the strain or product pages themselves, so readers cannot verify how a strain or product earned its position in a list. The site also runs a merchandise shop, medical-card referral service, and advertising program, none of which are disclosed on the ranking pages observed.

How the grade was reached

Independence · 30% weight 2 / 5

Does the site take money from the very entities it ranks? Pay-for-placement, vendor-funded data, and affiliate commissions all pull this down. The less the ranking can be bought, the higher the score.

Evidence basis · 30% weight 3 / 5

What is the ranking actually built on? Hands-on testing scores highest, then verified first-hand reviews, then opinion or popularity surveys and self-reported figures, then pay-to-rank, which scores lowest.

Method transparency · 20% weight 2 / 5

Is the methodology published, specific, and reproducible? Can a reader see how a given rank was reached, or is it a black box?

Conflict disclosure · 10% weight 1 / 5

Are commercial relationships, sponsorships, and affiliate arrangements disclosed clearly and near the rankings themselves, rather than buried?

Manipulation resistance · 10% weight 3 / 5

How hard is it to game? Controls against fake reviews, solicited reviews, and vendor gaming raise this; an open box anyone can stuff lowers it.
