If you have questions about speed vs meth, you are not alone. Speed and meth are both stimulants, but they are not exactly the same drug. Learning the real differences between them can help you make safer choices about your health.
Many people use these words interchangeably, but each term has its own meaning, risks, and effects. This article will break down what you need to know in simple terms.
Key Takeaways
- Speed and meth have differences in strength and use.
- Both affect your body and brain in powerful ways.
- Knowing the facts helps you understand the risks and get help if needed.
Understanding Speed and Meth
Amphetamine and methamphetamine are both stimulant drugs with similar chemical structures but important differences. The way people use, talk about, and experience these substances can vary depending on their form and origin.
Definitions and Terminology
Speed and meth are street terms often used to describe stimulant drugs.
Speed usually refers to amphetamine, a stimulant that affects your central nervous system. It can be found as a powder or pill. Meth usually means methamphetamine, which is stronger and longer-lasting. Meth can come in several forms, including powder, crystalline chunks (called crystal meth), or tablets.
Both drugs are illegal when used without a prescription. Meth is typically used recreationally, while some forms of amphetamine may be used as medication for conditions like ADHD but are tightly controlled. Misusing either drug is dangerous and can lead to serious health risks.
Chemical Composition and Structure
Both amphetamine (speed) and methamphetamine (meth) belong to a class of chemicals called phenethylamines.
Amphetamine’s chemical formula is C9H13N. Methamphetamine’s is C10H15N, which means it has an extra methyl group attached. This small change makes meth more powerful and longer-lasting than amphetamine.
Methamphetamine can pass through your brain barriers more easily, which results in stronger effects. It is usually found in its crystalline form (crystal meth/ice) or as a powder. Amphetamine, in comparison, is normally seen as an off-white powder or a pressed pill. This chemical difference is why meth is considered more addictive than amphetamine.
Drug | Chemical Formula | Strength | Common Forms |
---|---|---|---|
Amphetamine | C9H13N | Medium | Powder, Pills |
Methamphetamine | C10H15N | High | Powder, Crystal, Pills |
Street Names and Slang Usage
The words people use for these drugs can change depending on location, form, and culture.
Common slang for amphetamine (speed) includes:
- Speed
- Uppers
- Pep pills
- Bennies
For methamphetamine, you’ll hear names like:
- Meth
- Crystal
- Crystal meth
- Ice
- Glass
- Tina
- Shabu (popular in Southeast Asia)
Sometimes, base is used in some regions to mean a damp, oily form of amphetamine. Knowing these names can help you stay aware of what’s being talked about and avoid confusion.
Forms, Methods of Use, and Potency

Speed and methamphetamine can look different, be used in different ways, and have different strengths. Some forms are stronger and more dangerous than others.
Appearance and Physical Forms
Methamphetamine comes in several forms. The most common are crystal meth (white or clear, glass-like crystals), ice (large, clear crystals), base (waxy or oily paste), and powder (white or off-white powder).
Speed usually refers to amphetamine or methamphetamine in powder form, often white, pink, or yellowish. Sometimes, it is pressed into pills or capsules.
Crystal meth and ice are usually much purer and have a shiny, rock-like look. Base is sticky and can range in color from white to brown. These differences in appearance can help you identify which type you might be looking at or using.
Routes of Administration
You can use speed or methamphetamine in several ways, and how you use it can affect how quickly it works and how strong it feels.
- Snorting: Common for speed powder, which is crushed and inhaled through the nose.
- Swallowing: Both powder and pills can be taken by mouth.
- Injecting: Solution made from powder, base, or crystal is injected with a needle.
- Smoking: Crystal meth and ice are often smoked using a glass pipe because their form is easy to vaporize.
Smoked or injected forms act faster and feel stronger. Swallowing or snorting tends to have effects that take longer to start and may not be as intense.
Potency and Purity Differences
Not all forms are equally strong. Crystal meth and ice are usually the purest and have the highest concentration of methamphetamine, sometimes reaching up to 80% purity or more.
Speed powder is usually less pure and can be mixed with other substances to make it cheaper or easier to handle. This lowers the actual amount of methamphetamine you get with each dose.
Base sits somewhere between powder and crystal in both purity and strength. The method you use also changes how much of the drug enters your blood. Smoking or injecting sends more of the chemical into your body at once, making the effects stronger and riskier.
Effects on the Body and Brain

Both speed and meth belong to stimulant drugs that cause strong effects on your body and brain. They influence the way you feel, act, and think, and can have both short-term and long-term results depending on how and why you use them.
Central Nervous System Impact
Speed and meth are stimulants that affect your central nervous system. Once inside your body, they speed up messages between your brain and body.
You might notice more energy and alertness. You may feel less tired or hungry. These drugs can also raise your heart rate and blood pressure.
Taking high doses, or using them for a long time, can stress your heart and other organs. This can lead to health risks like heart attack, stroke, or seizures.
Neurotransmitters and Euphoria
Both speed and meth change how your brain uses dopamine, norepinephrine, and serotonin. These are called neurotransmitters.
Dopamine increases motivation and gives you feelings of pleasure or euphoria. Norepinephrine and epinephrine are responsible for wakefulness and alertness.
When you use these drugs, your brain releases large amounts of these chemicals. This sudden boost can make you excited, happy, or even invincible for a short time.
Your brain may stop making normal amounts of these chemicals after using these drugs for a while. This can cause sadness, tiredness, or trouble feeling joy.
Immediate and Long-Term Effects
Immediate effects include:
- Faster heart rate
- Higher blood pressure
- Increased energy
- Less appetite
- Faster breathing
Long-term effects can include:
- Addiction
- Memory problems
- Mood swings
- Dental problems (“meth mouth”)
- Trouble sleeping
Using these drugs over time can change the way your brain works and lead to mental health problems. You may also find it very hard to stop using them.
Medical Uses and Prescriptions
Not all stimulants are illegal or made illegally. Some, like Adderall and Desoxyn, are approved by doctors for certain health problems.
Doctors may prescribe amphetamine-based drugs for ADHD (attention deficit hyperactivity disorder) or narcolepsy. Prescription forms are controlled and made to be safe when used as directed.
The doses in prescription drugs are usually lower and given with a doctor’s guidance. Taking them the wrong way, or in high doses, can still be dangerous and risky.
The illegal use of speed or meth is not the same as using a prescription stimulant under a doctor’s care.
Addiction, Withdrawal, and Treatment

Both speed and meth have a high risk for addiction and can cause strong withdrawal symptoms. Treatment options include medical help and behavioral therapies to support recovery.
Addiction Potential and Substance Abuse
Speed and meth are both stimulants made from amphetamines, but meth is usually stronger and lasts longer in your body. This makes meth more addictive for most people.
You might become addicted quickly, sometimes in just a few uses, especially with meth. Substance abuse can lead to serious health problems, such as heart issues and brain changes. Many people start using these drugs to feel more energetic or alert, but they end up needing more to get the same effects.
Signs of addiction include taking more than planned, being unable to stop, and spending a lot of time getting or using the drug. Both drugs greatly increase your risk of substance use disorder.
Feature | Speed | Meth |
---|---|---|
Addiction Risk | High | Very High |
Duration | Shorter | Longer |
Common Form | Pills, Powder | Crystals, Powder |
Withdrawal Symptoms and Risks
When you stop taking speed or meth, you may face withdrawal symptoms. These can start within hours or days after your last dose.
Common withdrawal symptoms include:
- Fatigue
- Depression
- Anxiety
- Trouble sleeping
- Intense cravings
Meth withdrawal can feel worse than speed withdrawal because it’s usually stronger. Some risks are severe depression or even thoughts of self-harm. Cravings can last for weeks and may make you use again, even if you want to stop. The risk of relapse is high during withdrawal.
Addiction Treatment and Recovery
Addiction treatment for speed or meth usually starts with medical detox. Doctors may help you manage withdrawal symptoms in a safe place. You should not try to quit on your own if you have used heavily, as some symptoms can be serious.
Treatment programs may include:
- Inpatient rehab: You stay at a clinic for close support
- Outpatient care: You visit clinics while living at home
- 12-step groups: Peer support meetings
- Medical support: Medications for sleep, mood, or anxiety
Recovery is possible. Many people need several tries before quitting for good. The best outcomes happen when you have a mix of medical help and strong support.
Behavioral Health and Therapy Options
Behavioral therapy is a key part of treating addiction to speed or meth. These therapies help change your thoughts, habits, and reactions to triggers. Cognitive Behavioral Therapy (CBT) is common. It helps you avoid situations that lead to drug use.
You might have individual sessions, group counseling, or family therapy. Here are some options:
- CBT: Change negative thought patterns
- Contingency Management: Rewards for staying sober
- Motivational Interviewing: Build your reasons to quit
Therapies can help you find healthy ways to handle stress instead of using drugs. Support from mental health professionals is important for long-term recovery. Many treatment centers offer these behavioral options as part of their programs.
