420-friendly
420-friendly means a person uses cannabis, or is comfortable dating someone who does, stated openly as a profile compatibility signal.
On a dating profile, "420-friendly" signals a person's stance on cannabis before a conversation even starts. It covers two distinct groups under one label: people who consume cannabis themselves and are looking for a partner who also does or doesn't mind it, and people who don't consume but have no objection to a partner who does. The label does not indicate frequency or intensity of use. Someone can be 420-friendly and use rarely, or not at all, so the term functions as a tolerance marker more than a usage report. The number "420" traces to 1971 in San Rafael, California, where a group of high school students agreed to meet at 4:20 p.m. to search for an abandoned cannabis crop. The meetup became a recurring ritual, and "420" became their code word for cannabis. The term spread through cannabis culture over the following decades and became broader shorthand for "compatible with cannabis use." It also appears in housing listings and travel accommodations, alongside its now-common use in online dating. In practice, daters add "420-friendly" to a bio, or select it from a built-in lifestyle or substance-use preference field where the app offers one, to surface compatibility early and avoid an awkward disclosure later in the relationship. Because the term is intentionally vague about degree of use, it is common for one party to ask a direct follow-up question rather than assume a shared meaning. Related terms include "canna-curious," used for people newly interested in cannabis, and dedicated cannabis-dating platforms such as Blazr, built around the same compatibility premise.
