Key Takeaways

What are Blues (M30s)? Are They Dangerous?

M30s or “blues” are opiate-based prescription opioids. They contain 30 mg of oxycodone. The pills are stamped with an “M” logo on one end and the number 30 imprinted on the other.

Counterfeit versions of oyxcodone medication contain illegally manufactured fentanyl. Fentanyl is a synthetic opioid prescribed for severe pain. This is one of the most powerful prescription painkillers on the market. 

These fake M30s are made with a pill press and include fentanyl. The pills are sold by many drug dealers as real Oxy pills to unsuspecting buyers, fueling the nation’s opioid crisis.

However, it’s a highly addictive drug and very dangerous when misused. Counterfeit pills containing fentanyl vary in risk but can be deadly if they contain a dosage high enough to be fatal.

What are the Ingredients in Blues?

Blues are one of the most commonly abused painkillers. Due to the high illegal demand for the drug, they’re sometimes counterfeited or laced with fentanyl. Fentanyl is stronger and deadlier than oxycodone.

Each 30 mg tablet contains 27 mg of oxycodone. They also contain:

  • Polysorbate 80
  • Red iron oxide
  • Black iron oxide
  • Yellow iron oxide

Side Effects of Blues

Blues trigger a variety of common and dangerous side effects, including:

  • Nausea
  • Vomiting
  • Headache
  • Constipation
  • Confusion
  • Dizziness
  • Dry Mouth
  • Fever
  • Abnormal Dreams
  • Seizures
  • Insomnia
  • Death

There is also a high risk of opioid overdose for anyone using blues or M30s. Signs of a fentanyl overdose include:

  • Confusion
  • Slurred speech
  • Pale, clammy skin
  • Nausea
  • Vomiting
  • Blue lips/fingernails
  • Slow breathing or breathing stoppage
  • Slowed heart rate
  • Loss of consciousness

The risk of overdose is higher when this drug is mixed with heroin, cocaine, or other benzodiazepines.

Overdose is a medical emergency. If you believe you or someone you know has overdosed on blues, seek immediate medical attention or call 911.

Signs of Addiction to Blues

Blues are extremely addictive, especially when the drug is laced with fentanyl. 

Sides of addiction include:

  • Mood swings
  • Decrease in motivation
  • Loss of interest in once-loved activities
  • Avoiding family and friends
  • Physical tolerance (needing a larger dose to achieve the same effect)
  • Withdrawal symptoms when not using the drug

How to Avoid Counterfeit Drugs

All misused drugs pose a risk to users. This is especially true with illicit or street drugs. 

One of the greatest risks associated with illicit or recreational drugs is not knowing what you’re getting. Drug traffickers or anyone involved in the illegal drug market sometimes lace unknown substances into illicit drugs. Ideally, you’ll avoid all illegal drugs.

Their taste and smell are also the same. One way to know if they contain unknown substances is to test them. You can do this with rapid testing strips that detect fentanyl.

However, the only way to be certain you aren’t taking fentanyl-laced drugs is to avoid street drugs completely. Oxycodone should only be used when prescribed by a healthcare provider.2

Treatment Options for Addiction

Several treatment options for addiction are available for addiction to Blues. A comprehensive approach is usually the best option for most people with drug use problems.

Treatment options include:

Inpatient Treatment

This is an intensive treatment option that provides full-time supervision in a sober living environment. Most inpatient programs last for at least 30 days or longer.

Inpatient treatment usually includes a variety of treatment approaches, including:

  • Medically supervised detox
  • Medication-assisted treatment (MAT)
  • Group counseling
  • Individual counseling and psychotherapy
  • Peer support groups

Outpatient Treatment

This type of treatment combines access to some of the tools used during inpatient treatment, but it doesn’t remove someone from their regular life. 

People with opioid addiction in outpatient programs don’t stay overnight at the treatment facility.

Outpatient programs typically include:

  • Individual counseling
  • Group therapy
  • Access to medication
  • 12-Step Programs

12-step programs, including Narcotics Anonymous, offer access to peer support. These programs use the traditional 12-step approach introduced by Alcoholics Anonymous. They can be used alone or paired with other treatment approaches.


Blues, also known as M30s or a lookalike of oxycodone, are a type of commonly abused prescription painkiller. In addition to different brands, there are also counterfeit street versions. Many of these illicit versions are laced with fentanyl. 

Blues are highly addictive and frequently abused. Drug treatment programs are available for people addicted to blues.
