Adolescence: Physical & Mental Development — NEET Biology

📚 Practice Concept
📖 NCERT Source

Adolescence means both 'a period' and 'a process' during which a child becomes mature in terms of his/her attitudes and beliefs for effective participation in society. The period between 12-18 years of age may be thought of as adolescence period. In other words, adolescence is a bridge linking childhood and adulthood. Adolescence is accompanied by several biological and behavioural changes. Adolescence, thus is a very vulnerable phase of mental and psychological development of an individual.

Which of the following statements are NOT correct regarding addiction, dependence, and adolescence vulnerability to drug abuse? S1: Adolescence is a highly vulnerable phase for drug abuse due to curiosity and the perceived 'coolness' of substance use. S2: With repeated use of drugs, the body's tolerance level of receptors decreases, requiring smaller doses for the same effect. S3: Addiction refers to a physical withdrawal syndrome, whereas dependence is a psychological attachment to the drug's effects. S4: Drug dependence can be severe, potentially life-threatening, and often requires medical supervision during withdrawal. S5: Even a single instance of drug use can initiate the path to addiction due to the inherent addictive potential of these substances.
