Opioid Street Names, Risks, and What They Look Like

Opioids carry dozens of street names that vary by drug, region, and the specific pill being sold or traded.

Knowing what these names mean, what the drugs look like, and why slang develops around them is one of the most practical tools for recognizing opioid misuse in someone close to you.

The language around opioids changes constantly. Pills are resold under nicknames, described in coded terms, and referenced in conversations where the actual drug name never appears. Understanding the terminology is not about judgment. It is about staying informed and knowing what to look for before someone you care about is at risk.

What Are Opioids?

Opioids are a class of drugs that bind to mu-opioid receptors throughout the central nervous system, producing pain relief, euphoria, and respiratory depression in proportion to dose and individual tolerance.

How Opioids Work in the Brain

Opioids bind to mu-opioid receptor subtypes concentrated in the brainstem, spinal cord, and limbic system. This binding suppresses pain signal transmission while releasing dopamine in the nucleus accumbens, producing the euphoric reinforcement that drives compulsive use and opioid use disorder.

Chronic mu-opioid receptor activation triggers neuroadaptation and receptor downregulation, requiring progressively larger doses to produce equivalent effects. Abrupt discontinuation reverses this process, producing noradrenergic rebound hyperactivity, hyperalgesia, and autonomic instability.

Why Opioid Street Names Exist

Street names simultaneously obscure what is being discussed, signal membership in a social network, and provide plausible deniability when pills are described in terms that do not appear on any prescription label.

According to NIDA, families who can identify drug terminology are better positioned to recognize early warning signs and initiate conversations before dependence becomes established. Slang recognition is a documented harm reduction tool, not an invitation to panic or accusation.

Street Names for Common Opioids

Every opioid class carries its own vocabulary, and the same drug may carry different names across different regions, communities, and age groups.

Oxycodone

Oxycodone hydrochloride is sold under the brand names OxyContin (extended-release), Percocet (with acetaminophen), and Roxicodone (immediate-release). It is classified as a DEA Schedule II controlled substance.

The most common oxycodone street names include:

Legitimate oxycodone 30mg tablets are small, round, and blue. Counterfeit versions mimicking the M30 appearance are now widespread and frequently contain illicitly manufactured fentanyl rather than oxycodone.

Oxycodone-acetaminophen combination products carry dual toxicity risk. Opioid-induced respiratory depression occurs at elevated doses. Cumulative acetaminophen hepatotoxicity produces dose-dependent liver damage at daily amounts exceeding 3,000 to 4,000 milligrams.

• Blues, 30s, M30s: The 30mg immediate-release tablet, typically blue and stamped with “M30” or similar pharmaceutical imprints, is the most widely referenced oxycodone pill on the street.
• Percs: Short for Percocet; used loosely for any oxycodone-acetaminophen combination tablet regardless of dose.
• Roxy, Roxies: Refers specifically to Roxicodone immediate-release tablets in 5mg, 15mg, and 30mg formulations.
• OCs, Oxys, Hillbilly Heroin: Historical slang terms for OxyContin extended-release tablets, less common since reformulation but still in circulation.

Hydrocodone

Hydrocodone bitartrate is sold under the brand names Vicodin, Norco, and Lortab, all combined with acetaminophen, and as Zohydro ER without acetaminophen. It is a DEA Schedule II controlled substance and one of the most frequently misused prescription opioids in the United States.

The most common hydrocodone street names include:

Hydrocodone tablets are oblong or oval and appear white, yellow, or light orange depending on the manufacturer and dose. Imprint codes include “NORCO 5,” “WATSON 540,” and “M366.”

Dependence on hydrocodone can develop within weeks of daily use at prescribed doses. Before Schedule II reclassification in 2014, hydrocodone combination products were the most prescribed drug in the United States, contributing significantly to current opioid use disorder prevalence.

• Vikes, Vics: Short for Vicodin; refers to the 5mg/325mg hydrocodone-acetaminophen tablet.
• Hydros, Tabs: General street terms for any hydrocodone tablet regardless of brand or dose.
• Norco, Watsons: Norco is used colloquially; Watsons refers to tablets stamped with Watson pharmaceutical imprints.

Dilaudid and Hydromorphone

Hydromorphone hydrochloride is the generic name for Dilaudid. It is classified as a DEA Schedule II controlled substance and is four to eight times more potent than morphine at clinically equivalent doses.

The most common Dilaudid street names include:

Immediate-release Dilaudid tablets are small and round, available in 2mg (white), 4mg (yellow), and 8mg (orange), stamped with imprints including a triangle above the number designation. Injectable hydromorphone is a clear or amber liquid sold in small ampules.

Hydromorphone’s high lipid solubility allows faster central nervous system penetration than morphine, producing rapid-onset respiratory depression. Users who develop tolerance to street heroin and switch to street Dilaudid frequently underestimate the potency difference, producing accidental overdose.

• Dillies, Dillys: Short for Dilaudid; the most widely recognized street name for hydromorphone.
• D, Big D: Shorthand used in text messages and street transactions.
• Hospital Heroin: Refers to Dilaudid’s clinical use in inpatient pain settings and its potency relative to street heroin.
• Juice: Refers specifically to Dilaudid in injectable liquid formulation.

Fentanyl

Fentanyl citrate is sold under brand names Duragesic (transdermal patch), Actiq (buccal lozenge), and Subsys (sublingual spray). Fentanyl is dangerous as it is classified as a DEA Schedule II controlled substance and has a mu-opioid receptor binding affinity 50 to 100 times greater than morphine.

The most common fentanyl street names include:

Counterfeit M30 pills are visually identical to legitimate oxycodone tablets. A lethal fentanyl dose is approximately two milligrams, smaller than a few grains of salt. Per the CDC, fentanyl now drives more than 70% of opioid overdose deaths in the United States.

• Blues, M30s, Pressed Blues: Counterfeit pills manufactured to visually replicate oxycodone 30mg tablets but containing illicitly produced fentanyl at uncontrolled concentrations.
• China White, China Girl: Refers to pharmaceutical-grade fentanyl powder used in illicit manufacturing.
• Fetty, Fent: General slang for fentanyl in loose powder or pressed pill form.
• Fentalog: References fentanyl analogs including carfentanil, acetylfentanyl, and butyrfentanyl found in street supply.

Morphine

Morphine sulfate is sold under brand names MS Contin and Kadian in extended-release formulations. It is classified as a DEA Schedule II controlled substance and is the reference opioid against which all others are measured using the oral morphine equivalent scale.

The most common morphine street names include:

MS Contin extended-release tablets are round or oval in purple-gray and stamped with dose designations across the 15mg to 200mg range. Tolerance to morphine develops faster than to most other opioid classes because of the drug’s relatively straightforward receptor kinetics without active metabolite accumulation.

• M, Morph: General slang for morphine in any formulation.
• Miss Emma: Phonetic play on “M” and morphine used in older drug communities.
• Monkey, White Stuff: Historical terms still found in some regional markets.
• Blue Morphine: Refers specifically to blue-colored morphine tablets in specific dosage formulations.

Codeine

Codeine phosphate is sold in Schedule V low-dose cough syrups, Schedule III acetaminophen combinations, and Schedule II pure tablet formulations. Promethazine-codeine prescription cough syrup is the form most frequently misused for recreational purposes.

The most common codeine street names include:

Promethazine-codeine syrup is a thick, pink or purple liquid dispensed in prescription bottles. Codeine tablets are white or off-white and vary in size by dose and formulation.

Codeine is metabolized by the CYP2D6 enzyme into morphine to produce analgesia. In CYP2D6 ultra-rapid metabolizers, standard doses produce morphine concentrations high enough to cause fatal respiratory depression. In poor metabolizers, codeine produces no analgesia, creating dose escalation and accumulation toxicity risk.

• Lean, Syrup, Purple Drank, Sizzurp: Refers specifically to promethazine-codeine cough syrup mixed with soda, typically in a foam cup.
• Schoolboy, Captain Cody: Historical slang for codeine tablets still found in some communities.
• T3s: Refers to Tylenol 3, a combination tablet containing 30mg codeine with 300mg acetaminophen.

Methadone

Methadone hydrochloride is sold under the brand name Dolophine and is classified as a DEA Schedule II controlled substance. It is prescribed for pain management and as Medication-Assisted Treatment for opioid use disorder through licensed opioid treatment programs.

The most common methadone street names include:

Methadone 40mg wafers are round, white, and marked with dose designations. Oral liquid formulations are clear or cherry-flavored. Tablets range from 5mg to 40mg in white or off-white appearance.

Methadone has an unusually long half-life of 24 to 36 hours, causing plasma accumulation with repeated dosing. Fatal respiratory depression can occur days after the last dose as concentrations peak, a pattern not seen with shorter-acting opioids and one that complicates street use significantly.

• Wafer, Fizzies: Refers to the 40mg dispersible tablet used in opioid treatment programs, which dissolves in liquid.
• Dolls, Dollies: Derived from the brand name Dolophine.
• Jungle Juice, Metho: Regional terms for liquid methadone formulations dispensed at clinics.

Heroin

Heroin, chemically known as diacetylmorphine, is classified as a DEA Schedule I controlled substance with no accepted medical use in the United States. It is produced from morphine extracted from opium poppy plants and is the most common illicit opioid before the current fentanyl contamination era.

The most common heroin street names include:

Black tar heroin is sticky, dark brown to black, and sold in small wrapped chunks. Powder heroin ranges from white to brown depending on purity and cutting agents. White powder is most commonly associated with fentanyl adulteration in the current supply.

Opioid use disorder involving heroin carries the highest current overdose risk because street supply purity is entirely unpredictable and fentanyl contamination is pervasive. Naloxone reversal of heroin overdose may require multiple doses when fentanyl is present at elevated concentrations.

• H, Horse, Smack: Historical street terminology that remains in wide use across all geographic markets.
• Dope, Junk: General terms used for black tar or powder heroin without distinguishing between forms.
• Brown Sugar, Brown: Refers to brown or tan powdered heroin at lower purity grades.
• Chiva, Boy: Regional terms used in specific U.S. geographic markets.

How to Recognize Opioid Misuse

Recognizing opioid misuse early depends on understanding the behavioral and physical patterns that accompany regular opioid use, dependence development, and active opioid use disorder.

Behavioral Warning Signs

Behavioral indicators associated with opioid misuse include:

• Unexplained financial problems, missing cash, or requests to borrow money without clear explanation for what it is needed.
• Increasing secrecy around phone use, new social connections, or unexplained time away without clear accounting.
• Doctor shopping, requesting early prescription refills, or reporting opioid medication as lost to obtain additional prescriptions from multiple providers.
• References to opioid street terminology such as blues, 30s, Roxies, Dillies, Lean, or Fetty in messages, conversations, or social media activity.
• Declining academic or professional performance and withdrawal from activities and relationships that previously held consistent value.

Physical Warning Signs

Physical signs associated with active opioid use include:

• Pinpoint pupils that do not dilate normally in response to low light, a direct pharmacological effect of mu-opioid receptor activation on the pupillary reflex arc.
• Pronounced drowsiness, nodding off during conversation, or slurred speech inconsistent with the time of day or apparent fatigue level.
• Slowed breathing, reduced respiratory rate, or pale clammy skin indicating degree of opioid-induced respiratory depression.
• Track marks, bruising, or unexplained puncture wounds on the arms, hands, or feet in individuals who inject opioids intravenously.

The Counterfeit Pill Problem

Counterfeit opioid pills are now the leading driver of overdose mortality. Pills sold as oxycodone 30mg Blues or M30s routinely contain illicitly manufactured fentanyl rather than oxycodone. A buyer cannot visually distinguish a counterfeit from a legitimate pill.

Per the CDC, fentanyl concentration in street pills is inconsistent even within the same batch. One pill may contain a sub-threshold dose while an adjacent pill contains a lethal concentration. This inconsistency makes managing the physical risks of opioid withdrawal and dependence a clinical necessity, not a personal choice.
