"Because the impacts of problem drug users are largely hidden, and also because their number is actually relatively small (approximately 330,000; Hay et al., 2008),22 people’s understanding of problem drug use tends to come from remote sources – the media (including the internet, television, films, magazines and books) and anecdote – rather than from direct experience. This provides fertile ground for the growth of myths and stereotypes: for example, the prevalent belief in instant addiction and the myth of the drug dealer offering free drugs at the school gates."
