Final answer:
The potency of opioids refers to their ability to relieve pain. Methadone, Morphine, and Oxycodone have similar potencies, but Heroin is an outlier as its potency is significantly higher.
Step-by-step explanation:
The potency of opioids refers to their effectiveness in relieving pain. Methadone, Morphine, and Oxycodone have relatively similar analgesic effects. However, the outlier in this group in terms of potency is Heroin. Heroin is synthesized from morphine and is significantly stronger than the other opioids listed. This higher potency makes it a particularly dangerous drug, as it can easily lead to overdose.
It's also important to remember that the misuse of these substances can lead to serious health problems, and they should only be used under medical supervision.
