    Key Takeaways​

  • Stimulants speed up the body's systems. They can be prescription or illicit drugs.
  • Misusing stimulants is dangerous. It can lead to serious short- and long-term health problems including addiction, heart damage, mental health issues, overdose, and even death.
  • There are no approved medications to treat stimulant use disorder, but behavioral therapies and support services are available.
  • Prescription stimulants are safe when prescribed by a trusted medical professional, filled by a licensed pharmacy, and taken only by the person they are prescribed to and exactly as prescribed.  ​

What are stimulants?

Stimulants are drugs that speed up the body's systems. They are sometimes called “uppers." 

Stimulants include:

  • ​Prescription drugs (used to treat conditions like attention deficit hyperactivity disorder [ADHD], narcolepsy, and obesity)
    • Adderall® 
    • Dexedrine® 
    • Concerta® 
    • Ritalin® 
  • Caffeine
  • Illicit drugs*
    • Methamphetamine (“meth")
    • Cocaine
    • MDMA (“molly"/ecstasy)
    • Methcathinone and other synthetic cathinones (“bath salts")

*The term “illicit drug" refers to drugs that are illegal (e.g., methamphetamine, cocaine, etc.) or pills not obtained from a pharmacy or doctor/medical professional (e.g., counterfeit Ritalin, counterfeit Adderall, etc.). Illicit stimulant use carries serious health and legal risks.

​Stimulants are often used to help people stay awake, feel more alert, improve focus, or to “get high." They can cause feelings of euphoria, increased energy, and a reduced appetite. Stimulants can be misused (meaning not taken as prescribed) and are addictive. Using high doses over time can lead to serious problems like agitation, aggression, panic, suicidal or violent thoughts, and other negative health problems. Prescription stimulants are safe when prescribed by a trusted medical professional, filled by a licensed pharmacy, and taken only by the person they are prescribed to and exactly as prescribed.

  • Addiction ​


Withdrawal symptoms include:

  • Mood swings
  • Depression
  • Tiredness
  • Anxiety​
  • Drug cravings
  • Sleep problems
  • Pain 


Other serious consequences:

  • Accidental fatal or non-fatal overdose or "overamping"
  • Premature death due to health problems or accidental injuries
  • Complications during pregnancy such as premature birth, low birth weight, or placenta separating from the uterus  
  • Lifelong learning and memory problems linked to maternal use during pregnancy​

Stimulants are especially dangerous when:

  • Mixed with alcohol or other drugs
  • Used while driving
  • Taken alone with no help nearby​
  • A person has a mental health condition
  • A person has a heart condition
  • Used during increased physical activity
  • Used when the temperature is hot​

​Additional risks of methamphetamine use:

  • Damage to the liver, kidneys, and lungs
  • Severe tooth and gum problems
  • Early bone loss (premature osteoporosis)
  • Repeat infections (including skin sores from intense scratching)​

​Mixing Drugs is Especially Dangerous

Stimulants that are not prescribed by your doctor could be mixed with fentanyl. Fentanyl is an extremely strong synthetic (human-made) opioid that cannot be seen, smelled, or tasted when mixed into other drugs. Even a small amount of fentanyl can be deadly.

Fentanyl test strips (FTS) (PDF) can be used to check if fentanyl is present in a drug but they cannot show how much fentanyl is present. It's important to know that testing stimulants for fentanyl usually requires more water than testing opioids. Learn how to use FTS.

Whether done on purpose or by accident, mixing drugs significantly increases the risk of harm. Never mix prescription medications without a doctor's guidance.

When drugs are taken together, they can interact in dangerous ways. For example, mixing drugs or mixing drugs with alcohol can raise the risk of overdose.

​Stimulants Come in Many Forms

Stimulants can appear as powders, pills, liquids, or crystal-like rocks. Methods of use include smoking, inhaling, swallowing, snorting, or injecting. The drugs may look like colorful pills, white or brown powder, or shiny blue-white rocks.

People can take stimulants by smoking, inhaling, swallowing, snorting, or injecting the drugs. Pills and powder can be white, colorful tablets, brown crystalline powder, or shiny blue-white rocks.

Cocaine is a white, crystal-like powder made from coca leaves. It can be snorted, smoked, swallowed, or dissolved and injected. Its other names include "coke," "snow," and "flake." Learn more about coc​aine (PDF).​

Crystal methamphetamine is a synthetic stimulant. It looks like glass fragments or shiny blue-white rocks. It is often smoked with a glass pipe, but can also be swallowed, snorted, or injected. Other names for crystal meth include "ice" or "glass." Learn more about crystal methamphetamine (PDF). crystal meth
Methamphetamine is a pill or powder that can be smoked, snorted, swallowed, or injected. A prescription version (Desoxyn®) is sometimes used to treat ADHD or obesity. Its other names include "meth," "speed," and "crank." Learn more about methamph​etamine (PDF).

MDMA (Ecstasy) is a synthetic drug with both stimulant and hallucinogenic effects. It is usually taken as a pill, capsule, or liquid. It is often called a “party drug." Its other names include "lover's speed," "hug drug," "molly" and "x." Learn more about M​DMA (PDF).
MDMA (ecstasy)
Prescription stimulants are medicines used to increase alertness, attention, or energy. They are used to treat medical conditions such as ADHD, narcolepsy, and obesity. Common examples include Dexedrine®, Adderall®, Ritalin®, and diet aids. They come in tablet, capsule, or liquid form and can be swallowed, injected,  snorted, or smoked. Learn more about prescription stimulants.

Synthetic cathinones ("Bath Salts") are human-made stimulants that often look like a white or brown crystal-like powder. They are marketed as plant food, jewelry cleaner, glass cleaner, research chemicals, bath salts, and labeled "not for human consumption." Synthetic cathinones can be snorted, smoked, ingested, or injected. Other names include "vanilla sky," "cloud nine," and "white lightning." Learn more about synthetic c​athinones (PDF).

Treatment

There are currently no approved medications to treat stimulant use disorder. The most effective treatment is behavioral therapy, such as counseling, contingency management, and support programs. There are also no currently approved medications to reverse a stimulant-related overdose. Naloxone doesn't work to reduce the effects of a stimulant. However, if you're not sure what drug someone took, always give naloxone - they may have unknowingly taken an opioid, like fentanyl. Naloxone has very few negative effects, and has no effect if opioids are not in a person's system.

What is California doing?

CDPH's Substance and Addiction Prevention Branch (SAPB) monitors fatal and non-fatal stimulant-related overdose trends over time in California, by sex, age, race/ethnicity, and substance type. These indicators and trends are also available by geography, county, and zip code on the California Overdose Surveillance Dashboard.

  • For stimulant-related overdose deaths, stimulants tracked include psychostimulants with abuse potential (e.g., methamphetamine, MDMA, dextroamphetamine, levoamphetamine, or methylphenidate (Ritalin)) and cocaine.

  • For stimulant-related non-fatal overdose emergency department visits or hospitalizations, stimulants tracked include amphetamines and cocaine.

CDPH SAPB works with many partners throughout the state to monitor and address current trends at the state and local level. Working closely with local health departments, drug safety coalitions, and other partners at the local level allows CDPH to support local prevention and intervention efforts that address the unique trends and specific needs of California's communities. Efforts include:
  • Connecting partners to improve health care access and health equity

  • Supporting harm reduction services & holistic approaches to wellness

  • Building community engagement to reduce stigma

  • Statewide surveillance to provide data for evidence-based decisions
