What's drug addiction?
Drug addiction, drug abuse, and similar terms have become very judgmental. The terms also aren't very specific. That's why doctors prefer the term "substance use disorder" for when people can't stop using substances that harm them.
What causes a substance use disorder?
Not everyone who uses a substance has a substance use disorder. Although almost anyone can develop a substance use disorder, your risk is greater if:
The substance is very pleasurable and easy to get
You don't believe the substance is that dangerous
You often feel sad, lonely, or anxious
You have certain psychiatric disorders, such as some personality disorders or major depression

Your risk also is increased if you take prescription opioid painkillers for a painful injury or chronic pain. Opioids, though a legitimate way to control pain, are highly addictive.
What are the symptoms of a substance use disorder?
With a substance use disorder, you may:
Not be able to control use of the substance: You take it even when you know it's bad for you
Have tolerance to the substance: You need to use more and more of it to get the same effect
Experience withdrawal: You get unpleasant symptoms when you stop using the substance
How can doctors tell if someone has a substance use disorder?
Sometimes people tell their doctor they're having a problem. Or doctors may suspect you have a substance use disorder if you:
Spend a lot of time getting, using, or recovering from the effects of the substance
Want to stop using the substance but can't
Have a strong craving to use the substance
Can't meet your responsibilities at work, school, or home because of the substance
Use the substance in dangerous situations, such as when driving
Give up social or work activities because of the substance
Tolerance and withdrawal also are signs of substance use disorder, unless they develop while you're using the substance legitimately. For example, you may have opioid withdrawal after taking opioids for less than a week, which may be necessary for certain painful injuries, such as severe burns.
Although urine and blood drug tests can tell if you have drugs in your system, they can't tell if you have a substance use disorder.
