Long Term Effects of Drug Addiction

The long term effects of drug abuse and addiction can seriously affect one's life in school, at work, and in relationships.? Here are some examples:

  • Poor school performance. Studies show that grades go down as alcohol consumption increases. The average student who has one drink a day earns a GPA of only a C-level. Greater usage is associated with failing grades. 30% of academic problems stem from alcohol misuse.
  • ?Poor work performance. People with drug abuse problems miss more work days, are less productive, have more problems with their bosses, and make more mistakes, including on-the-job injuries.
  • Relationship trouble. Drug abuse puts a strain on relationships. Problem drinkers and drug abusers tend to change social circles often and are unable to maintain long term friendships. They alienate themselves from others to hide their excessive consumption.
  • Personality changes. Drastic personality changes can result from drinking or using drugs. A normally quiet person may become boisterous or obnoxious, even violent, under the influence of alcohol and other drugs. Marijuana has been linked to "amotivational syndrome" in which people lose interest in their jobs, friends, and lives. Long term abuse of drugs such as cocaine, amphetamines, and LSD can cause psychosis.
