Substance Abuse

Drug addiction, also called substance use disorder, is a disease that affects a person’s brain and behavior and leads to an inability to control the use of a legal or illegal drug or medication. Substances such as alcohol, marijuana and nicotine also are considered drugs. Addicts typically continue drug-use despite knowing the harm that it causes.

Drug addiction symptoms or behaviors include:

• Feeling that you have to use the drug regularly — daily or even several times a day
• Having intense urges for the drug that block out any other thoughts
• Over time, needing more of the drug to get the same effect
• Taking larger amounts of the drug over a longer period of time than you intended
• Making certain that you maintain a supply of the drug
• Spending money on the drug, even though you can’t afford it
• Not meeting obligations and work responsibilities, or cutting back on social or recreational activities because of drug use
• Continuing to use the drug, even though you know it’s causing problems in your life or causing you physical or psychological harm
• Doing things to get the drug that you normally wouldn’t do, such as stealing
• Driving or doing other risky activities when you’re under the influence of the drug
• Spending a good deal of time getting the drug, using the drug or recovering from the effects of the drug
• Failing in your attempts to stop using the drug
• Experiencing withdrawal symptoms when you attempt to stop taking the drug
