From use to addiction
Drug or substance abuse is harmful use of a psychoactive substance: a substance that can change mood, thinking, judgement, behaviour, or body function. The substance may be legal, such as tobacco or alcohol; controlled, such as some sedatives and pain medicines; or illegal, such as heroin or illicit cannabis products. For public health, the key issue is the pattern of use: repeated or risky use despite harm to health, studies, family relations, money, safety, or law-abiding behaviour.
Use means taking a substance in a limited and legitimate setting, such as a prescribed medicine taken exactly as advised. Misuse means using it wrongly: taking extra tablets, using another person's prescription, mixing medicines with alcohol, or using a substance in an unsafe setting. Harmful use means damage has begun. Dependence means the body or mind has adapted so strongly that the person struggles to function without the substance. Addiction means compulsive use despite clear damage, with craving and loss of control dominating behaviour.
Tolerance means needing more of a substance to get the same effect, or getting less effect from the same amount. Withdrawal means physical or mental distress when the substance is reduced or stopped; symptoms vary by substance and may include restlessness, sweating, tremors, poor sleep, anxiety, irritability, body pain, nausea, or confusion. These points matter because drug abuse is not just a "bad habit"; it is a health, behaviour, family, and social problem that needs early support.
