Is Weed Legal in Illinois in 2026?
Yes — recreational and medical cannabis are both legal in Illinois. Illinois made history in 2019 as the first state to legalize recreational marijuana through the legislature (rather than a ballot initiative). The state is also a major destination for cannabis tourism, drawing visitors from neighboring states where marijuana remains illegal.
