What happened: The WNBA removed marijuana from its banned substances list in the league's new players' agreement. The same document added psilocybin, DMT and ibogaine to the prohibited list for the first time, according to the source signal.

Why it matters: The change moves cannabis policy closer to broader shifts in pro sports and state law while drawing a new line around psychedelic substances. It also gives players and teams a clearer labor-agreement framework for discipline, treatment and compliance during the 2026 season.

What to watch: Watch for how the league and players' association explain enforcement details. Any future discipline or medical-policy guidance will show how the new language is applied in practice.
