Young people who vape are more likely to use marijuana, according to a study published Monday. The findings, researchers say, support the theory that nicotine rewires the developing brain, changing how people respond to and crave addictive substances.
“Adolescents have a brain that’s still changing and developing,” said Dr. Nicholas Chadi, the lead author on the study, who conducted the research as a fellow in pediatric addiction medicine at Boston Children’s Hospital and Harvard Medical School.
When a young brain is exposed to an addictive substance such as nicotine, it “tends to be sensitized to other substances; it tends to seek a thrilling, rewarding sensation,” said Chadi. “And so other substances like marijuana become more appealing.”
