A new study conducted on laboratory animals reveals that menthol significantly intensifies and prolongs the effects of nicotine within the body. Researchers found that the addition of menthol to e-cigarettes boosts nicotine's impact, suggesting flavored vapes may be more addictive. The study specifically focused on the effects of menthol, a common flavoring agent in many e-cigarette products. These findings raise concerns about the potential for increased nicotine dependence among users, particularly young people. Experts suggest the reinforcing effect of menthol could counteract efforts to reduce smoking and vaping rates. Further research is needed to fully understand these implications and inform public health policies regarding e-cigarette regulation in Greece.
