Atmospheric air contains about 21% oxygen, but medical-grade oxygen is a highly concentrated gas (at least 82% pure) and classified as a prescription drug. The question of 'How does oxygen work as a drug?' is key to understanding its therapeutic use for conditions where patients aren't getting enough on their own.

Oxygen is the most abundant element by mass in the Earth's crust, but this essential component of our air has a complex identity. For those in healthcare and scientific fields, the question "does oxygen count as a substance?" leads to a nuanced answer that depends heavily on the context, particularly within the realms of chemistry and pharmacology.
