This is a broad question so I’m not 100% sure how to answer. Dispensaries with recreational licenses will be allowed to sell cannabis to those 21 yrs and older starting Jan. 1. However, not every dispensary will have a rec license. Furthermore, some cities and counties are not allowing recreational sales at all. In this sense, nothing is getting postponed; some places are just not ready to sell rec and some may never be willing to.
