Have you ever encountered a small, round white pill stamped with “M” on one side and “3” on the other? This seemingly harmless tablet—often called the M 3 pill—is intended to ease moderate pain, but like any opioid-based medication, it also carries serious risks when misused.

What Is the M 3 Pill?

The M 3 white round pill is a small, circular tablet with “M” imprinted on one side and “3” on the other. Manufactured by Mallinckrodt Pharmaceuticals, this prescription opioid contains 30 mg of codeine phosphate and 300 mg of acetaminophen. Many search for M 3 pill round white, pill with M and 3, or white round pill M 3 to confirm its identity and effects.

The M 3 round white pill is classified as a Schedule III controlled substance due to its potential for abuse and dependence. It is commonly prescribed under the brand name Tylenol #3 and is sometimes referred to on the street as:

  • Captain Cody
  • Cody
  • Schoolboy

What Is the M 3 Round White Pill Used For?

The M 3 pill is used for managing moderate pain that does not respond to over-the-counter pain relievers. Its medical applications include:

  • Post-surgical pain relief
  • Chronic pain management
  • Injury-related pain relief

How Strong Is the M 3 Pill?

Compared to stronger opioids like oxycodone or morphine, the M 3 pill has a lower potency, but that does not mean it is safe for misuse. 30 mg of codeine is considered a moderate opioid dose, but taking multiple pills or mixing them with other depressants can lead to dangerous effects.

When used as prescribed, the M 3 round white pill provides pain relief and mild sedation. However, in high doses, codeine metabolizes into morphine, which enhances its opioid effects and increases the risk of respiratory depression and overdose.

Does the M 3 Pill Get You High?

Yes, the M 3 white round pill can cause a high, but the effects depend on the dose, tolerance, and metabolism. Since codeine is weaker than oxycodone or hydrocodone, the high is milder but still habit-forming.

People who misuse the M 3 pill to get high often describe:

  • Euphoria (a warm, relaxed sensation)
  • Mild sedation and drowsiness
  • Lightheadedness and dizziness
  • Tingling or numbing sensations

How Long Does White Round Pill M 3 Last?

The effects of the white round pill M 3 typically follow this timeline:

  • Onset: 30 to 45 minutes after ingestion
  • Peak effects: 1 to 2 hours after ingestion
  • Duration: 4 to 6 hours

Risks of M 3 White Round Pill

1. Overdose Risk

Taking too much codeine can cause severe respiratory depression, where breathing slows or stops completely. CDC research warns that mixing opioids with alcohol or benzodiazepines significantly increases the risk.

2. Acetaminophen Toxicity

The M 3 pill contains 300 mg of acetaminophen, which is toxic to the liver in high doses. Exceeding recommended doses can lead to acute liver failure (FDA).

3. Addiction and Dependence

Using round white pill M 3 beyond 10-14 days can significantly increase addiction risks (NIDA).

Is the M 3 Pill Used to Make Lean?

While some individuals crush the M 3 pill and mix it with soda, the traditional version of lean (purple drank) typically relies on codeine-promethazine cough syrup. Misusing the M 3 pill to create lean increases the risk of overdose and liver failure.
