Final answer:
Tina is likely to engage in other unhealthy behaviors, such as smoking, drinking alcohol, and early involvement in sexual activity. Drug addiction is characterized by compulsive substance use despite negative consequences. Research suggests a link between early substance abuse and other risky behaviors.
Step-by-step explanation:
Tina is likely to engage in other unhealthy behaviors, such as smoking, drinking alcohol, and early involvement in sexual activity. Late puberty tends to be more difficult than early puberty. Those who mature later than their peers may feel physically inferior and develop poor body image and low self-esteem. This can contribute to the development of unhealthy coping mechanisms, such as substance abuse.
Drug addiction is defined as the compulsive use of a substance such as a psychoactive drug despite negative consequences. Tina's increasing use of cigarettes, alcohol, and drugs throughout high school and late adolescence suggests a pattern of compulsive drug use.
Research studies have found a link between early substance abuse and other risky behaviors. For example, a study by Kaltiala-Heino et al. (2001) found that early puberty and early sexual activity were associated with bulimic-type eating pathology in middle adolescence. This suggests that engaging in one risky behavior, such as substance abuse, may increase the likelihood of engaging in other unhealthy behaviors.
