Any e-commerce site selling THC products should implement an age-gate pop-up requiring visitors to confirm they are 21 or older before accessing the site. While not universally mandated across all jurisdictions, this is a widely adopted industry practice and is considered a baseline compliance measure for THC-containing product lines.
The general principle: if a site sells THC products, implement the age gate. The friction cost to legitimate users is negligible, and the risk of omitting it outweighs the minor UX inconvenience.
Regulations vary by state and are evolving. Not all THC e-commerce sites currently implement age gates, but many do — particularly those selling Delta 9 THC products. The conservative and defensible position is to implement the gate regardless of whether it is strictly required in every jurisdiction where the site operates.
From the Fieldwell / Take 9 design review (Oct 17, 2025): Caitlin Doak raised the need for a 21+ age verification pop-up specifically because the site carries THC products. The team agreed that "better safe than sorry" was the right posture, noting that the gate is unlikely to deter legitimate buyers and provides meaningful legal cover.
