Co-use of cannabis and tobacco linked to poorer functioning among young adults

More than a third of young adults report using both cannabis and tobacco or nicotine products, providing a unique challenge to public health officials as cannabis is legalized in more jurisdictions, according to a new RAND Corporation study.

Studying a group of young adults from California, researchers examined the many different ways that cannabis and tobacco or nicotine products are used together—a byproduct of the introduction of new vaping devices and other delivery methods.

Among those surveyed, young adults who used cannabis and tobacco or nicotine together in some way (either using one right after the other or by mixing the products together) tended to consume more marijuana and tobacco or nicotine products, and report poorer functioning and more problematic behaviors compared to those who used did not use both products together. The study is published online by the journal Psychology of Addictive Behaviors.
