Key Points at a Glance
- 1
Substance abuse means harmful or risky use of a psychoactive substance when it damages health, studies, family life, safety, or law-abiding behaviour.
- 2
Repeated misuse may progress towards dependence or addiction; dependence is linked with craving, impaired control, tolerance, withdrawal, and continued use despite harm.
- 3
Common risk substances include tobacco and nicotine, alcohol, cannabis products, opioids, stimulants, sedatives, inhalants, and prescription medicines taken without medical need.
- 4
Broad exam categories are depressants, stimulants, hallucinogens, and opioids; the group matters because each affects the brain, behaviour, and emergency risk differently.
- 5
Youth are vulnerable because peer pressure, curiosity, stress, easy availability, online influence, and weak supervision can turn experimentation into repeated use.
- 6
Warning signs include sudden fall in studies, secretive behaviour, mood swings, red eyes, unusual smell, missing money, new risky friends, and loss of interest in healthy activities.
- 7
Prevention works best through awareness, family support, school counselling, refusal skills, sports and hobbies, early treatment, and community action.

From use to addiction
Drug or substance abuse is the harmful or risky use of a psychoactive substance. A psychoactive substance affects mental processes such as mood, perception, consciousness, cognition, judgement, or emotions. The substance may be legal, such as tobacco or alcohol, or illegal or controlled, such as heroin, charas, or sedatives taken without medical need. For public health, the key issue is the pattern of use: repeated use or unsafe use despite harm to health, studies, family relations, money, safety, or law.
Use means taking a substance in a limited or medically directed way, such as a prescribed medicine taken as directed. Misuse means using it wrongly, such as taking extra tablets, using another person's prescription, mixing medicines with alcohol, or drinking in an unsafe setting. Abuse is repeated harmful use. Dependence begins when the person feels unable to function normally without the substance. Addiction is compulsive use despite clear damage, where craving and loss of control dominate behaviour.
This is not an inevitable step-by-step ladder for every person. Some people may stop after early misuse; others may move quickly towards dependence. The exam-safe idea is that repeated misuse increases risk. Tolerance means the body needs a larger amount for the same effect. Withdrawal means unpleasant physical or mental symptoms appear when the substance is reduced or stopped, such as restlessness, sweating, tremors, poor sleep, anxiety, or body pain.
Remember: CET questions can test the difference between use, misuse, dependence, addiction, tolerance, and withdrawal.
