Stimulants: cocaine & meth
The high fades fast, but the brain can heal. Recovery from stimulants is real.
By the numbers
How common stimulant use is, and why the risks have grown.
Millions of people in the U.S. use cocaine or meth each year. Most are someone’s child, parent, partner or friend.

Overdose
What are cocaine and meth?
"Uppers" that flood the brain with a feel-good chemical.
Stimulants speed up the brain and body. Cocaine comes from the leaves of the coca plant. Methamphetamine ("meth") is made in labs. For a quick overview with street names and body effects, see the Substance Use guide.

Small amounts of cocaine usually make people feel happy, energetic, talkative and alert. When snorted, the high may last 15 to 30 minutes. When smoked, it peaks faster and fades in about 5 to 10 minutes.
Because the high is so short, people may use again and again in a short time. This raises the risk of harm.

Meth can bring a rush of happiness, energy and confidence within minutes. Effects can be felt right away or within about 20 minutes.
Meth can be very hard on the heart and brain, and can lead to anxiety, sleep problems and psychosis with long-term use.
How stimulants hook the brain
A dopamine surge teaches the brain to want more.
Cocaine causes a surge of dopamine, a brain chemical linked to pleasure and reward. That surge teaches the brain that the drug is a reward worth seeking again.

Over time, tolerance can build. A person may need larger amounts, use more often, or both, to feel the same high. This raises the risk of overdose.

With repeated use, people can feel more unhappy and low when they are not using. These are signs of withdrawal.

After stopping meth, low mood, anxiety and cravings can last for several months. Knowing this ahead of time helps people plan for it, instead of feeling like they are failing.
The high and the crash
What goes up comes down, and the comedown can be hard.
The high from meth fades quickly, which can lead to a "crash". When someone stops after repeated use, withdrawal usually peaks 2 to 3 days after the last use and can last about a week.
The comedown can bring
- Anxiety
- Cravings
- Irritability
- Low mood or depression
- Sleep problems
Mood, anxiety & paranoia
Why stimulants can make people feel on edge or unsafe.
Some people who use cocaine feel restless, irritable, anxious, panicky or paranoid. Paranoia means feeling like others are watching you or out to get you.

Meth’s immediate effects can include paranoia, anxiety and a fast heartbeat. Cocaine can bring panic and paranoia, especially with heavier use.

Long-term meth use may cause anxiety, confusion, sleep problems and mood changes. Some studies link it to slower reactions and trouble with verbal learning.

Many people with a substance use disorder also live with another mental health condition. People with depression, anxiety or PTSD are more likely to use substances. Some use to try to feel better when care is hard to reach.
Stimulants and psychosis
When the mind loses touch with what is real, and what helps.
Meth can cause psychosis. This can mean seeing or hearing things that are not there, or deeply believing things that are not true. These symptoms can happen even when a person is not high.
Heavy cocaine use can also bring psychosis. For someone who has had meth-related psychosis before, heavy drinking and stress can make it more likely to come back.
If someone you are with seems out of touch with reality
- Call 988 for guidance, or 911 if anyone is in danger
- Keep your voice low and calm
- Remove anything that could be used to cause harm, if it is safe to do so
- Stay with them, or nearby, if it is safe
The hidden fentanyl risk
Most stimulant overdose deaths now involve an opioid too.
Fentanyl, a very strong opioid, is often mixed into cocaine and meth. Many people do not know it is there. You cannot see, smell or taste it.
In 2021, nearly 8 in 10 overdose deaths involving cocaine, and about 2 in 3 involving meth and similar drugs, also involved an opioid. Because cocaine wears off quickly, a person may not feel how much opioid they took.
Why people use stimulants
There is always a reason, and it deserves understanding.
People use stimulants for many reasons. Knowing the reason helps find safer ways to meet the same need.

Stimulants bring a burst of energy and alertness. Some people use them to push through exhaustion or long hours. The crash afterwards often leaves them more tired than before.

Stimulants can make people feel confident and talkative. For people who feel shy, lonely or anxious, that can be a strong pull.

People with anxiety, depression, stress or trauma may use drugs to try to feel better, especially when care is hard to get.
Recovery & what treatment looks like
Talking therapies and small rewards are proven to help.
Behavioral treatments are the main proven approach for cocaine and meth use. NIDA notes that using less is a meaningful step forward, too. Recovery does not have to be all or nothing.
Read more
Contingency management offers small, real rewards, like prizes, vouchers or gift cards, for staying drug-free and in treatment. It is the best-studied behavioral treatment for stimulant use and is especially useful early on.

CBT is an effective approach for cocaine use. In one study, adding a computer-based CBT program to counseling helped more people stay off cocaine, with benefits lasting up to 6 months.
Read more
Motivational interviewing is one of the evidence-based approaches for meth use. It helps people find their own reasons to change, without pressure.
Read more
Group support is part of evidence-based care for meth use. Some people also stay in a therapeutic community, a live-in recovery program that may last 6 to 12 months.
How community helps
Respect and connection make recovery more likely.
Labels like "junkie" or "user" make people feel less than human, and can keep them from asking for help. Person-first words, like "a person who uses meth", keep the person in view.
Ways anyone can help
- Invite someone to sober plans, like a meal, a walk or a game
- Know the emergency signs and when to call 911
- Listen without lecturing, and ask how you can help
- Use person-first language, and gently correct stigma when you hear it
