Oxycodone M30 (Blue)

A blue M30 oxycodone tablet is a prescription opioid pain medication. The authentic pharmaceutical version has these characteristics:
Medication: Oxycodone (immediate-release)

Imprint: M on one side and 30 on the other (often written as "M 30")
Color: Blue
Shape: Round
Manufacturer: Mallinckrodt (SpecGx)
Prescription status: Prescription only
Controlled substance: Schedule II in the U.S. due to its high potential for misuse and dependence.
Medical uses
Oxycodone is prescribed for the treatment of moderate to severe pain, especially when non-opioid pain medicines are not effective enough.
How it works
Oxycodone is an opioid that binds to opioid receptors in the brain and spinal cord, reducing the perception of pain.

Counterfeit warning
Blue M30 tablets are among the most commonly counterfeited prescription pills. Counterfeit versions are often made to look nearly identical to genuine tablets but may contain Fentanyl or other unexpected substances instead of, or in addition to, oxycodone. Because appearance alone cannot distinguish a genuine pill from a counterfeit one, pills obtained outside a licensed pharmacy carry a significant overdose risk.
If you're trying to identify a specific blue M30 tablet, tell me:
whether it has M on one side and 30 on the other,
its approximate diameter,
and where it came from (licensed pharmacy or another source).
