Descriptive cross-sectional survey of tobacco and cannabis restrictions on state and local film incentives in the USA.

Film incentives are large financial commitments that may undermine public health since they allow depictions of tobacco and cannabis that contribute to initiation and use. Few states or localities limit film incentives related to tobacco or cannabis, and the existing restrictions are unlikely to deter depictions or product placement. Restrictions on incentives are an underused tool for deterring tobacco and cannabis depictions in film.
