Drug addiction refers to the compulsive and repeated use of increasing amounts of drugs with the appearance of withdrawal symptoms when drug use ceases. While the specific causes of drug addiction are not known, genetic, psychological and environmental factors are thought to play a significant role. Rather than a single cause of drug addiction, it is likely multiple factors lead to drug addiction in any given person.
Some drug addicts also identify drug use and ignorance as a cause of drug addiction. Often, if a person is dealing with pain-management issues, the drug they receive, like oxycodone, can be very addictive. The ignorance of the drug's addiction potential, along with the physical pain of the condition, becomes a cause of drug addiction.
