Substance abuse can simply be defined as a pattern of harmful use of any substance for mood-altering purposes. Medline 's medical encyclopedia defines drug abuse as "the use of illicit drugs or the abuse of prescription or over-the-counter drugs for purposes other than those for which they are indicated or in a manner or in quantities other than directed."
Generally, when most people talk about substance abuse, they are referring to the use of illegal drugs. Most professionals in the field of drug abuse prevention argue that any use of illegal drugs is by definition abuse. Those drugs got to be illegal in the first place because they are potentially addictive or can cause severe negative health effects; therefore, any use of illegal substances is dangerous and abusive.
Others argue that casual, recreational use of some drugs is not harmful and is merely use, not abuse. The most vocal of the proponents of recreational drug use are those who smoke marijuana. They argue that marijuana is not addictive and has many beneficial qualities, unlike the "harder" drugs.
Drug abuse is a problem that involves communities as much as it does individual users. Drug abuse can increase family stress, crime and significant health problems. Treatment programs, designed to reduce the negative effects of drug addiction within a community, are costly to implement and are not always effective.

Family Stress
In addition to causing marital stress, drug addictions also place children of users at greater risk of emotional problems, physical problems and learning difficulties. These children may engage in patterns of codependent behavior, merely enabling a parent 's drug abuse.
Crime
In order to support expensive drug habits, users sometimes engage in crimes such as robbery, prostitution or even aggressive panhandling. Consequently, citizens within communities that experience related spikes in crime urge law-enforcement officials to take action.
