Definition
An opioid drug used as a painkiller and as a cough suppressant, available by prescription and sometimes found in combination cold or pain medications. Codeine causes drowsiness, slowed reaction time, impaired judgment, and dizziness, and is disqualifying for flight operations while it is in the pilot's system.
Plain English
A prescription pain and cough medicine that dulls the brain and slows you down. You cannot fly while it is still working in your body.
Context Anchor
Seen in aviation medical and drug-use discussions, especially when deciding whether a medication is safe before a flight.
Derivation
From the Greek 'kodeia,' meaning 'poppy head.' Codeine is extracted from the opium poppy, the same plant that produces morphine. Knowing it is an opioid signals immediately that it belongs to the family of drugs that impair alertness and coordination.
Why Pilots Care
Use of codeine is prohibited for pilots because it impairs alertness and decision-making, increasing accident risk. Pilots must wait until the drug is fully cleared before operating aircraft.
Intuition Check
Do not assume “prescribed” means “safe to fly.” With codeine, the key question is whether the medicine can impair alertness, reaction time, or judgment.
Example Sentence 1
After his dentist prescribed a codeine-based painkiller, the pilot grounded himself for several days until the medication had fully cleared his system.
Example Sentence 2
FAA rules require pilots to disclose any codeine use and stay on the ground until medically cleared.
