An increase of smoking behaviors is likely, related to possible social interactions (e.g. restaurants.). We found no study related to smoking behaviors and quarantine. Smokers exposed to natural disasters tend to smoke more than unexposed smokers (Huh J, Timberlake DS. Do smokers of specialty and conventional cigarettes differ in their dependence on nicotine? Addict Behav 2009; 34:204–11). A Japanese study conducted three years after the 2011 earthquake and tsunami reported an increase of tobacco consumption (Koyama et al., 2020). Former smokers are also more likely to relapse (Lanctot et al., 2008). The actual pandemic may have long-term deleterious effects on smoking behaviors.
