Amphetamine Street Names: Common Slang & Identification

Most families I work with had no idea what their son or daughter was using until they stumbled across a word they didn’t recognise in a text message. The slang shifts fast, especially in Southeast Asia where yaba and shabu have almost completely replaced older Western terms. By the time a parent googles a term, the circle of users may already be on to something new. What doesn’t change is the pharmacology, whichever name is on it, you’re dealing with a dopamine and norepinephrine dump that the brain was never designed to sustain.

What Are Amphetamine Street Names and Why Do They Exist

Street names for amphetamines exist for one reason: to talk about drug use in plain sight without being understood by police, parents, or employers. They vary by country, city, age group, and subculture. A term that’s common in Sydney may mean nothing in Bangkok or London.

The language also serves a psychological function. Calling a drug “go-fast” or “zip” makes it sound less serious than what it actually is: a powerful central nervous system stimulant that floods the brain’s reward circuitry with dopamine. Normalising the name normalises the use.

These are the most widely documented amphetamine slang terms, organised by category. Regional prevalence is noted where it matters clinically.

Amphetamine vs Methamphetamine Street Names: What Is the Difference

This is the question that trips up most families. Amphetamine and methamphetamine are related but not identical, and their street names often overlap. Speed, for example, can refer to amphetamine sulphate powder in the UK and to methamphetamine in North America. Crank was historically amphetamine paste but now almost always means methamphetamine in current usage.

Methamphetamine is roughly two to three times more potent than amphetamine for equivalent doses. It crosses the blood-brain barrier faster and produces a more intense dopamine release. The street names for methamphetamine, particularly ice, glass, and Tina, tend to cluster around the crystal form, which is almost always smoked or injected rather than swallowed or snorted.

For a detailed comparison of how these two drugs differ pharmacologically, see this breakdown of amphetamine versus methamphetamine.

Yaba and Shabu: Amphetamine Street Names in Southeast Asia

If you are in Thailand, the Philippines, or anywhere across Southeast Asia, the amphetamine slang you need to know is different from the Western list above.

Yaba, which means “crazy medicine” in Thai, is a tablet form combining methamphetamine with caffeine. Tablets are typically red or orange and stamped with “WY” or “R”. They are swallowed or smoked off foil. Yaba is the most widely used illicit stimulant in Thailand by volume.

Shabu refers to crystal methamphetamine and is the dominant term in the Philippines and parts of Thailand. It is typically smoked using a glass pipe or injected. The purity of shabu varies enormously, and cutting agents including fentanyl have been documented in supply chains in recent years.

If someone you know is using yaba or shabu, the effects of crystal methamphetamine are the clinical reference point, not classic amphetamine toxicology.

How Amphetamines Are Used and Why the Route Matters

The street name rarely tells you how the drug is being used, and the route of administration changes the risk profile significantly.

Smoking and injecting produce what users call the “rush”, an immediate, intense surge driven by rapid dopamine receptor saturation in the nucleus accumbens. The brain remembers this intensity precisely, and that memory is a central driver of compulsive use. Oral use produces a slower curve with less euphoria, but the addiction liability is still significant.

What Amphetamines Actually Do in the Brain

Street slang describes the experience. Pharmacology explains why that experience becomes a trap.

Amphetamines work primarily by forcing neurons to release dopamine and norepinephrine, and by blocking the reuptake transporters (DAT and NET) that would normally clear them. The result is a dopamine flood roughly ten times higher than anything food or sex produces naturally. The brain’s reward system, built on DAT and D2 receptors, reads this as the most important event that has ever happened.

With repeated use, the brain compensates. It downregulates D2 receptor density and reduces natural dopamine synthesis. The user now needs amphetamine just to feel baseline normal. This is the neurobiological substrate of addiction, described systematically in the Koob-Volkow model of the addiction cycle.

The serotonin transporter (SERT) is also affected, particularly at higher doses, which is why mood crashes, paranoia, and hallucinations follow heavy binges. Some of these neurological effects, especially dopaminergic neurotoxicity in the striatum, can persist for months after stopping.

Physical Signs of Amphetamine Use Families Should Know

Knowing the street name is only step one. Recognising use in someone you care about requires knowing what to look for clinically.

Short-term signs include pupils that are notably enlarged (mydriasis), reduced appetite, elevated energy and talkativeness followed by a sharp crash, jaw clenching, and excessive sweating at rest. Sleep may be absent for 24 to 48 hours during a binge.

Longer-term signs are more severe. Significant weight loss, dental erosion from dry mouth and bruxism (the “meth mouth” pattern seen with heavy methamphetamine use), skin picking from formication (the sensation of insects under the skin), and stimulant-induced psychosis that can be clinically indistinguishable from paranoid schizophrenia on first presentation.

Amphetamine Slang and Drug Testing: What Families Need to Know

A common question from parents and partners: “If I know the name, can I test for it?”

Standard urine drug screens detect amphetamine and methamphetamine. A positive for “speed” or “whiz” will typically show as amphetamine on the panel. Yaba and shabu will show as methamphetamine because that is their active component. Detection windows in urine are generally two to four days for single use and up to one week for heavy, chronic use.

Saliva testing detects amphetamines for approximately one to two days post-use. Hair follicle testing can detect use going back up to 90 days but is not widely available in all clinical settings.

One important point: prescription medications matter here. Lisdexamfetamine (Vyvanse), dextroamphetamine (Dexedrine), and mixed amphetamine salts (Adderall) are legitimate medications that will trigger positive amphetamine screens. If someone tests positive, always ask about current prescriptions before drawing conclusions.

Amphetamine Addiction Treatment Options

Recognising the street name that someone is using is often the starting point for a family realising there is a serious problem. The clinical question after that is what treatment looks like.

There is currently no approved pharmacotherapy for amphetamine use disorder in the way methadone or buprenorphine exist for opioids. The most evidence-supported treatments are behavioural: Cognitive Behavioural Therapy (CBT), contingency management, and structured residential treatment. The ADAPT trial and Matrix Model have the most robust data for methamphetamine specifically.

Medical support is still essential, particularly in the first days of withdrawal. The crash after stopping heavy amphetamine use can produce severe depression, suicidal ideation, and profound sleep disruption. Monitoring and symptom management during this period reduce dropout and prevent harm.

For those in Thailand, structured options exist. Phuket Island Rehab offers residential treatment that addresses both the neurobiological and psychological dimensions of stimulant use disorder. For a detailed look at what that involves, see the amphetamine addiction treatment options in Thailand page.

The DSM-5 defines stimulant use disorder across a spectrum from mild to severe, based on criteria that include continued use despite relationship or health consequences, inability to cut down, spending significant time obtaining or recovering from the drug, and craving. You do not need to be injecting daily to meet criteria. Many people using “speed” on weekends for months meet the threshold for moderate stimulant use disorder without recognising it.

At Phuket Island Rehab, we work with people across the full spectrum, from early-stage use that has started affecting work and relationships to severe dependence following years of daily use. Treatment is structured, medically supervised, and tailored specifically to stimulant use rather than the generic rehab model that treats every addiction identically.

Amphetamine street names, from speed and whiz in the UK and Australia to yaba and shabu in Southeast Asia, are a moving target. They shift by region, subculture, and decade. What does not shift is the pharmacology: regardless of the name on the street, these drugs force a massive dopamine release through DAT blockade and reverse transport, and repeated exposure rewires the brain’s reward circuitry in ways that can persist long after the drug is stopped. The route of administration matters as much as the drug itself. Smoking and injection produce faster onset, more intense euphoria, and faster progression to dependence than oral or intranasal use.

For families, the practical priority is pattern recognition, not slang fluency. The physical signs of chronic stimulant use (weight loss, dental erosion, disrupted sleep, paranoia) are consistent regardless of what the drug is called locally. If those signs are present, the name on the street is less important than getting a clinical assessment. Treatment works. CBT and contingency management have solid evidence behind them, and structured residential care adds the medical oversight that the withdrawal and early recovery period genuinely requires. As John A. Smith of Phuket Island Rehab puts it: “Families waste weeks trying to figure out exactly what the drug is called. I tell them: the name doesn’t change what I see in clinic, and it doesn’t change what we need to do next.”

What is the most common street name for amphetamine?

Speed is the most widely used street name for amphetamine globally, particularly in the UK and Australia where it refers to amphetamine sulphate in powder or paste form. In North America, uppers and crank are also common, though crank now more often refers to methamphetamine. In Southeast Asia, yaba and shabu have largely replaced older Western slang.

Is “ice” the same as amphetamine?

Ice is crystal methamphetamine, not amphetamine sulphate. The two are related but distinct compounds. Methamphetamine is more potent, faster acting, and produces a more intense dopamine release than standard amphetamine. They are both stimulants in the same drug class, but their potency and addiction trajectory differ significantly. For a detailed comparison, the pharmacological difference between amphetamine and methamphetamine is worth understanding before assuming they are interchangeable.

What does “yaba” mean and what drug is it?

Yaba means “crazy medicine” in Thai, and it refers to a tablet that combines methamphetamine with caffeine. Tablets are usually red or orange, stamped with “WY” or similar markings, and are either swallowed or smoked off foil. Yaba is the most commonly used illicit stimulant in Thailand and much of Southeast Asia. Because its active ingredient is methamphetamine, it carries the same addiction and health risks as crystal methamphetamine.

How long does amphetamine stay in your system for a drug test?

Amphetamine is detectable in urine for two to four days after single use and up to seven days with heavy, chronic use. Saliva tests detect it for approximately one to two days. Hair follicle testing extends the detection window to up to 90 days. Prescription amphetamine medications such as lisdexamfetamine and dextroamphetamine will also trigger a positive result, so disclosure of any current prescriptions is essential before interpreting a test.

What are the signs someone is using amphetamines?

The clearest short-term signs are enlarged pupils, significantly reduced appetite, elevated energy or talkativeness, jaw clenching, and going without sleep for one or more nights. With ongoing use, look for rapid weight loss, dental erosion, skin picking, and erratic or paranoid behaviour. A crash following a period of stimulant use typically produces extreme fatigue and low mood, which is often when families notice something is wrong.

Can you get addicted to prescription amphetamines?

Yes, though the risk is substantially lower when medication is taken at prescribed doses for a genuine medical condition such as ADHD. Addiction risk increases sharply when amphetamines are used at higher doses than prescribed, taken by a person without the condition being treated, or used in ways other than oral administration (snorting or injecting). Dextroamphetamine and mixed amphetamine salts diverted from prescriptions are a documented source of misuse, which is reflected in street names like “dexies” and “kiddie speed.”

What is the difference between “base” and “speed”?

Both base and speed refer to amphetamine, but the form differs. Speed typically refers to amphetamine sulphate in powder form, which is usually snorted or swallowed. Base refers to amphetamine in a wet, paste-like free base form, which is generally more concentrated and is often swabbed on the gums or swallowed. Base tends to have a higher amphetamine content by weight than powder speed, meaning the dose risk per gram is higher.
