Final answer:
The most common opiates are heroin and codeine, which are natural opioids derived from the opium poppy. They are joined by synthetic opioids like oxycodone and fentanyl in having a high potential for abuse and contributing to the opioid crisis. The correct option is B.
Step-by-step explanation:
The most common opiates are heroin and codeine, making the correct answer to the question 'b'. These substances are derived from the opium poppy plant and are used for their analgesic properties, which means they decrease pain.
However, they also carry a high potential for abuse due to the way they interact with the body's opioid receptors, producing euphoria in addition to pain relief.
Opioid drugs can be either natural such as the opium derivatives morphine and codeine, or synthetic, such as oxycodone and fentanyl. Heroin, which is made by chemically modifying morphine, is particularly known for being strongly addictive.
Prescription drugs such as hydrocodone (Vicodin), oxycodone (OxyContin), and methadone are also opioids and have been associated with the opioid crisis due to their potential for misuse and abuse.
