Stimulants are a class of drugs that increase activity in the brain and body. They can boost alertness and attention, but they can also harm one’s health. Some stimulants can be prescribed and safely monitored by a doctor, but others, including cocaine and methamphetamine, are illegal and carry serious risks.
While many people associate overdose risk primarily with opioids, stimulants are also involved in a significant number of overdose deaths. In 2024, more than 28,000 overdose deaths involved psychostimulants with abuse potential, such as methamphetamine, and nearly 22,000 involved cocaine. Understanding these risks can help individuals and families recognize when stimulant misuse has become dangerous and when it’s time to seek support.
Stimulants Put Stress on the Body
Stimulants can create a temporary sense of euphoria, confidence, energy, and focus. Methamphetamine, in particular, causes a rapid release of dopamine, a brain chemical involved in motivation and reward. This can make the drug highly reinforcing, as the brain begins to associate misuse with reward and urges the person to continue.
At the same time, stimulants speed up the body’s systems. Even small amounts of methamphetamine can increase blood pressure, cause faster breathing, trigger a rapid or irregular heartbeat, and interfere with sleep and appetite.
These effects can become especially dangerous for people with existing heart conditions, high blood pressure, anxiety, trauma histories, or other mental health concerns.
Heavy or repeated use can increase the risk of chest pain, heart attack, stroke, seizures, and overheating. Over time, stimulant misuse can also contribute to anxiety, paranoia, insomnia, hallucinations, mood changes, and aggressive or erratic behavior.
Stimulant Misuse Can Affect Judgment
Stimulants also affect decision-making. When someone is misusing stimulants, they may feel more alert or in control than they actually are. This can make it easier to take risks or combine substances without fully considering the consequences. Over time, repeated stimulant misuse can make cravings stronger and make it harder to stop, even when the person sees the impact on their health, relationships, work, or responsibilities.
This is one reason stimulant use disorder can be difficult to recognize early. A person may believe they are only using occasionally, but misuse can progress, especially when the brain begins to rely on the drug for energy or motivation.
Polysubstance Misuse Increases the Danger
One of the most serious risks of stimulant misuse is polysubstance misuse. Combining substances can make it harder to predict the effects of each drug. Alcohol and cocaine, for example, can place additional strain on the heart and increase impulsive decision-making. Stimulants may also mask the sedating effects of other substances, causing someone to misuse more than they realize.
Polysubstance use is especially dangerous when the synthetic opioid fentanyl is involved. People may not be able to see, taste, or smell fentanyl in another substance, and many people don’t know they’ve taken it until an overdose occurs.
For someone who intends to misuse a stimulant, fentanyl exposure can be especially deadly because they may have little or no opioid tolerance and aren’t prepared for the respiratory depression fentanyl can cause. Naloxone can reverse an opioid overdose, but emergency medical help is still needed.
Prescription Stimulants Still Carry Risk
Prescription stimulants can be effective when used as directed for conditions such as Attention-deficit/hyperactivity disorder (ADHD). The risk increases when they’re taken without a prescription, at higher doses than prescribed, or used for reasons such as staying awake, studying longer, losing weight, or enhancing performance.
This type of misuse can be easy to minimize because the medication may have come from a friend, classmate, coworker, or family member. But prescription stimulants still affect the heart, brain, and nervous system. They can also cause dependence, anxiety, insomnia, and other health concerns when misused.
People who are prescribed stimulant medication should take it exactly as directed and avoid sharing it with anyone else. If the medication no longer feels effective, or if there is an urge to take more than prescribed, it’s important to speak with a healthcare provider rather than adjusting the dose independently.
Signs Someone May Need Help
Stimulant misuse can look different from person to person. Some signs may be physical, while others may show up in behavior or mood. Warning signs may include:
- Sleeping very little or staying awake for long periods.
- Increased anxiety, irritability, paranoia, or agitation.
- Rapid speech, restlessness, or unusual energy.
- Unexplained weight loss or appetite changes.
- Chest pain, racing heartbeat, or overheating.
- Strong cravings or difficulty cutting back.
- Continuing to misuse despite problems at work, school, home, or in relationships.
- Misusing multiple substances or using alone.
- Withdrawal symptoms such as depression, fatigue, headaches, sleep problems, or intense cravings.
Any chest pain, seizure, loss of consciousness, severe confusion, or suspected overdose should be treated as an emergency.
Addiction Recovery for Stimulant Misuse is Possible
Stimulant use disorder is treatable. While there are currently no FDA-approved medications specifically for methamphetamine addiction, evidence-based behavioral therapies can help.
- Cognitive-behavioral therapy can help people identify triggers, build coping skills, and change patterns that contribute to use.
- Motivational incentives (contingency management) can also support addiction recovery by reinforcing progress and substance-free behaviors.
Addiction recovery treatment can also address co-occurring mental health concerns, trauma, stress, housing instability, relationship challenges, and other factors that may contribute to substance misuse.
With the right treatment, support, and addiction recovery plan, people can regain stability and move forward.
