Adolescence and the onset of puberty have both a physiological and social impact on a developing person. About half of grade 12 students have been drunk, and a third binge drink. About 3% drink every day. One of these social impacts is the increase in risk-taking behaviors, such as the emergence of alcohol use. Children aged 16 and under who consume alcohol heavily display symptoms of conduct disorder. Its symptoms include troublesome behaviour in school, constantly lying, learning disabilities and social impairments.
