Substance use disorders are associated with a wide range of short- and long-term health effects. They can vary depending on the type of drug, how much and how often it’s taken and the person’s general health. Overall, the effects of drug abuse and dependence can be far-reaching. They can impact almost every organ in the human body.
Side effects of drug addiction may include:
- A weakened immune system, increasing the risk of illness and infection
- Heart conditions ranging from abnormal heart rates to heart attacks and collapsed veins and blood vessel infections from injected drugs
- Nausea and abdominal pain, which can also lead to changes in appetite and weight loss
- Increased strain on the liver, which puts the person at risk of significant liver damage or liver failure
- Seizures, stroke, mental confusion and brain damage
- Lung disease
- Problems with memory, attention and decision-making, which make daily living more difficult
- Global effects of drugs on the body, such as breast development in men and increases in body temperature, which can lead to other health problems
The most severe health consequences of drug abuse is death. Deaths related to synthetic opioids and heroin have seen the sharpest rise. In the past 12 months, 212,000 people aged 12 or older have used heroin for the first time. Every day, more than 90 Americans die after overdosing on opioids.
