Unsafe movies: "Watching many modern movies may be a health hazard, particularly for impressionable teenagers, an Australian researcher suggests. Scientists analysed 87 of the most popular films of the past 20 years, counting 53 sex scenes in about a third of the movies, yet found only one suggestion of using a condom. They found 8 per cent of the blockbusters included scenes involving cannabis, 7 per cent contained episodes of non-injecting illicit drug use, 32 per cent depicted alcohol intoxication and 68 per cent had actors smoking tobacco. They said the movies tended to portray drug use in a positive light and nothing of the consequences."
