Name an example of an Opioid.
Answer: B — Codeine
Codeine is considered an example of an Opioid because it is a natural alkaloid found in the opium poppy plant. It is commonly used as a pain reliever and cough suppressant. LSD, marijuana and nitrous oxide are not classified as Opioids as they are not chemically similar to natural opioids and do not have the same effects on the body.
