SAN DIEGO (KSWB/KUSI) -- Teens and young adults who use cannabis may be significantly more likely to become regular tobacco users later on, according to new research led by the University of California, San Diego.
The study, published this week in the journal Tobacco Control, found that cannabis use among youth may be responsible for roughly 13% of new cases of regular tobacco use in the United States.
“This study challenges long-held assumptions about the pathways between cannabis and tobacco use among youth,” said corresponding study author Karen Messer, Ph.D., professor at the UC San Diego Herbert Wertheim School of Public Health and Human Longevity Science and director of biostatistics at UC San Diego Moores Cancer Center.
