Drugs are substances that lead men to carelessness about their own bodies. These become sick and degenerate. Judgement is impaired and men make mistakes in their work, their driving, their relationships with others. Their families and dependents too are affected by the errors of judgement which result from their carelessness. The Buddha pinpoints that it is the carelessness resulting from taking drugs that causes errors in our thinking and behaviour. This carelessness is avoided if the cause, the drugs themselves are given up.
