What does drug addiction do to a person's physical health?

Les explains that unless a person is fortunate enough to be drawn out of and broken of their drug problem, it will utterly destroy their physical health. He compares this to the alcoholic, whose liver and whole physical well-being are eventually destroyed, and to cigarettes, which medical science has proven do much the same thing. Les says that if you harm the physical body with things you know are harmful, it will suffer the consequences. He recalls a doctor on Good Morning America saying the American people could lower skyrocketing medical costs simply by stopping the things that harm their body, and he noted that roughly 70% of hospital beds are occupied by people there because of drinking, smoking, drugs, or venereal diseases. Les concludes that hospital beds are filled with people who have abused their physical bodies with harmful things, and that is all the Bible is telling us.
