Tobacco-free nicotine can come from products such as e-cigarettes, oral nicotine pouches and nicotine gum. Researchers examined whether dependence on these products was associated with recovery after burn injuries.
After matching similar patients, the study compared 20,906 people with tobacco-free nicotine dependence with 20,906 without recorded nicotine dependence. The nicotine-dependent group had higher rates of several complications within 90 days and higher mortality and newly diagnosed opioid use disorder at one year.
