San Diego, CA—A recent population-based study of 1,000 California smokers followed for 1 year suggests that e-cigarettes may not be a useful smoking-cessation tool. The study, conducted at the University of California, San Diego School of Medicine, found that smokers who used e-cigarettes were 59% less likely to quit smoking and 49% less likely to decrease cigarette use, compared with smokers who never used e-cigarettes. The researchers, who had hypothesized that smokers using these products would be more successful at quitting, say further studies are needed to determine why e-cigarette users cannot quit, but surmise that they may be receiving an increased nicotine dose from these devices.
