Drug Abuse: Types and Prevention MCQ - Practice Questions with Answers

Tolerance is the body's adjustment in which a larger amount is needed to get the same effect that a smaller amount produced earlier. Withdrawal is different: it means discomfort such as restlessness, sweating, tremors, poor sleep, anxiety or body pain when the substance is reduced or stopped. Dependence focuses on feeling unable to function normally without the substance. The clue in the question is needing more for the same effect, so the term is tolerance.

Alcohol can damage the liver, brain and nerves. Opioids can cause overdose because they may slow or stop breathing. Injecting drugs with shared needles raises the risk of infections. Inhalants can cause long-term damage to the brain and organs. These four cues give the matching alcohol with liver-brain-nerve damage, opioids with breathing suppression, shared needles with infection risk, and inhalants with brain and organ damage.

Limited or socially accepted use can move into misuse when a substance is taken wrongly, such as extra tablets or someone else's prescription. Abuse means repeated harmful use. Dependence begins when the person feels unable to function normally without the substance. Addiction is the later compulsive stage, where craving and loss of control continue despite clear damage. Therefore, use, misuse, abuse, dependence and addiction is the correct order.

Warning signs must be read as a cluster of academic, behavioural, physical and emotional changes. A single sign does not prove drug abuse because stress, illness, bullying or mental-health difficulty can also change behaviour. Falling marks, secrecy and red eyes can raise concern, but they call for calm observation, conversation, counselling and help when needed. Treating one sign as proof is therefore the incorrect statement.

School prevention includes life-skills education, trained counselling, teacher awareness, sports, cultural activities, and safe reporting systems. Community prevention uses awareness camps, local health workers, police, NGOs, and panchayat or urban bodies for support and referral. Family prevention is based on supervision, routine, trust, and open conversation. A student's refusal skill is the immediate action of saying no clearly, changing the topic, leaving the place, or calling a trusted person. These roles make the matching school-life skills, community-referral, family-supervision, and student-refusal the only complete fit.
