M367 refers to a pain reliever that melds hydrocodone bitartrate with acetaminophen. Acetaminophen is a non-opioid medication, whereas hydrocodone bitartrate is recognized as an opioid analgesic. Typically, M367 is formulated with a ratio of 10 mg/325 mg for hydrocodone bitartrate and acetaminophen, respectively, with hydrocodone being present in the smaller quantity.

Obtaining M367 legally necessitates a prescription from a healthcare provider.


Given that M367 is administered orally, the medication is available in pill form. It presents as a white, oval-shaped pill resembling a capsule, featuring a debossed "M367" on one side and a bisecting line on the other.

Regrettably, individuals who misuse the drug often crush the pills into a fine powder for either snorting or injecting into the bloodstream. In this altered state, M367 becomes nearly indiscernible from other illicit substances.


Thanks to the amalgamation of hydrocodone bitartrate and acetaminophen in M367, the drug is employed to attain a diverse range of effects. Hydrocodone functions as an analgesic and antitussive agent, meaning it alleviates pain and suppresses coughing.

The mechanism involves a direct impact on the brain stem respiratory center, inhibiting involuntary cough reflexes. Additionally, the compound binds to opioid receptors, influencing how the brain interprets pain signals.

Similarly, acetaminophen, also known as paracetamol, serves as an analgesic and is renowned for its fever-reducing properties. The drug is frequently utilized to lower body temperature. Acetaminophen tablets are also often combined with other medications to achieve various effects. In the case of M367, acetaminophen complements hydrocodone bitartrate in the treatment of moderate to severe pain.

Effects on the Body

Being an opioid medication, hydrocodone bitartrate binds to opioid receptors located in the gut, nerve cells, spinal column, brain, and other components of the central nervous system. Upon attachment to these nerve receptors, hydrocodone bitartrate effectively blocks pain signals. Ingesting this medication results in a person no longer experiencing pain from an injury or illness.

The antitussive properties of the drug function in a similar manner by impeding or halting involuntary muscle movements that cause coughing. However, an excessive manifestation of this effect can lead to respiratory depression, a condition where the lungs become inefficient at gas exchange, particularly oxygen and carbon dioxide.

Conversely, acetaminophen tablets are generally considered safe. As a non-opioid substance, acetaminophen is not prone to causing dependence and seldom leads to overdosing. Acetaminophen achieves pain reduction by inhibiting the production of prostaglandins in the brain, subsequently diminishing the sensation of pain. The drug's cooling effect also aids in lowering body temperature, particularly in cases of fever.

Potential for Abuse

Acetaminophen tablets do not lead to the development of tolerance and are, therefore, not considered addictive. In contrast, hydrocodone bitartrate carries a high potential for abuse. As an opioid, extended use or misuse of the drug can lead to mental and psychic dependence or addiction.

When individuals use M367 to address persistent pain as prescribed, the likelihood of addiction is low. However, upon discontinuation of the medication, the person may experience physical withdrawal symptoms.

Addiction typically occurs when hydrocodone bitartrate is taken in excess of the prescribed dosage or duration advised by a medical professional. Both factors contribute significantly to the risk of developing dependence and addiction.

Differences Between M367 and L484


  1. Active Ingredients: M367 is associated with a combination drug that contains two active ingredients – hydrocodone bitartrate and acetaminophen. Hydrocodone is an opioid analgesic, and acetaminophen is a non-opioid pain reliever.
  2. Purpose: M367 is typically prescribed for the management of moderate to severe pain. The combination of hydrocodone and acetaminophen provides a dual mechanism for pain relief.
  3. Imprint: The imprint "M367" is specific to the manufacturer and the appearance of the pill. It is an oval, white pill with "M367" debossed on one side and a bisecting line on the other.


  1. Active Ingredient: L484, on the other hand, represents a single active ingredient – acetaminophen (paracetamol).
  2. Purpose: L484 is a plain acetaminophen pill and is commonly used to relieve pain and reduce fever. It lacks the opioid component present in M367.
  3. Imprint: The imprint "L484" is specific to the appearance of the pill and is associated with plain acetaminophen. It is typically a white, oblong-shaped pill.

Alternative to M367


Oxycodone is another opioid analgesic, and when combined with acetaminophen, it provides pain relief. Medications like Percocet fall into this category.

The Drug Enforcement Administration and M367

The primary U.S. government agency responsible for combating drug trafficking and distribution within the country is the Drug Enforcement Administration (DEA). Additionally, the DEA plays a crucial role in researching and categorizing different drugs based on their potential for abuse.

Does M367 Make You Feel High?

Yes, indeed, M367 can produce a euphoric sensation, especially when consumed in large quantities. Being a semisynthetic drug, hydrocodone bitartrate shares molecular similarities with codeine and morphine. These similarities allow hydrocodone to elicit a high comparable to that induced by other opioid narcotics.

As per the Drug Enforcement Administration (DEA), individuals taking M367 in smaller doses may experience an overall sense of warmth, contentment, and increased sociability with lowered inhibitions. In higher doses, the depressant effects of hydrocodone bitartrate become more pronounced. This can lead to feelings of lethargy or tiredness, accompanied by a drop in energy levels and a significant relaxation of muscles, which can pose risks.

It's important to note that opioid overdose is perilous and may potentially result in fatality. In cases of high M367 consumption, individuals may encounter clinically significant respiratory depression, characterized by slow and shallow breathing, which can be life-threatening.

M367 Side Effects

The reported M367 side effects commonly include sensations of lightheadedness, dizziness, nausea, and occasional vomiting. These adverse reactions are more noticeable in ambulatory patients, and non-ambulatory patients may experience a less pronounced impact. In some cases, lying down can alleviate some of these side effects.

Furthermore, M367 may affect the central nervous system, leading to drowsiness, mental clouding, lethargy, anxiety, fear, mood changes, and the development of psychic dependence. Psychic dependence involves a sense that one will not be okay without the drug, leading to fear and anxiousness. It's important to distinguish psychic dependence from physical dependence, which can result in physical withdrawal symptoms if the medication is not taken.

Identifying these adverse reactions is crucial, and individuals experiencing them should seek emergency medical attention from a healthcare provider.

Long-term Effects of M367 Dependence

Using M367 over extended periods, even in non-lethal doses, can lead to various detrimental effects on the body. Here are some of the harmful long-term effects associated with the drug.

  1. Respiratory IssuesM367 significantly impacts the body's respiratory system, and prolonged usage can result in various respiratory problems. Notably, individuals may experience irregular and shallow breathing, leading to additional physiological issues over time due to insufficient oxygen intake.
  2. ImmunosuppressionProlonged use of M367 can lead to immunosuppression, weakening the body's immune system and increasing susceptibility to infections. Opioids like hydrocodone can affect both the adaptive and innate immune systems, elevating the risk of conditions such as pneumonia. Additionally, the use of hydrocodone injections raises the likelihood of contracting HIV and AIDS, which severely impact the immune system.
  3. AddictionWhile dependence refers to the physiological need for the drug, addiction or substance abuse disorder is the neurological compulsion to continue drug consumption despite awareness of its harmful effects. This pervasive urge leads to maladaptive practices that harm physical health, social relationships, and other aspects of life.
  4. Gastrointestinal Tract IssuesOpioids affect involuntary muscles, and long-term use of hydrocodone can result in gastrointestinal problems. Individuals may experience abdominal pain, cramps, vomiting, and constipation. One severe consequence of opioid abuse is bowel obstruction, a medical emergency with potential lethality if left untreated.
  5. Severe WithdrawalCeasing M367 use for a brief period may lead to severe withdrawal symptoms due to dependence. Individuals may experience restlessness, insomnia, muscle cramps, shaking, stomach pain, fatigue, irregular heartbeat, and intense cravings for the drug. These withdrawal symptoms can complicate the recovery process, leading to relapses as individuals seek relief from the discomfort.
  6. Mood DisordersOpioids like hydrocodone can alter brain chemistry, contributing to mental health disorders such as depression and anxiety. Overcoming these more subtle effects of substance abuse often requires a combination of therapy and medication to support individuals on their journey to recovery.


The prolonged use of M367, a combination of hydrocodone bitartrate and acetaminophen, can have severe and lasting repercussions on an individual's health. From respiratory complications and immunosuppression to the risk of addiction and gastrointestinal issues, the toll on the body and mind is considerable. Additionally, the challenge of overcoming severe withdrawal symptoms and the potential development of mood disorders underscore the complexity of addressing substance abuse.

It is crucial for individuals facing M367-related concerns to seek timely medical attention and professional support. Recognizing the gravity of these long-term effects emphasizes the importance of informed decision-making and responsible use of medications, all while promoting a comprehensive approach to recovery that addresses both the physical and mental aspects of substance abuse. Ultimately, fostering awareness, education, and accessible resources is paramount in mitigating the detrimental impact of prolonged M367 use on individuals and society at large.
