Percentage of alcohol-consuming 15 and 16 year olds experiencing alcohol-related harm* by fake identification ownership**. Error bars on the figure represent 95% confidence intervals. * Participants were asked whether they had ever experienced one (or more) of the listed harms after drinking alcohol. Those who did not report experiencing any harms are listed here as no reported harm (n = 7,442). Harms explored include: forgetting things after drinking (n = 7,743), entering a car with a drunk driver (n = 7,822), having regretted sex after drinking (n = 7,286) and being violent when drunk (n = 7,673). **All of the comparisons between those who do and do not have fake identification are significant (chi square analysis, all P < 0.001; df = 1).
