Fentanyl is a powerful synthetic opioid used primarily to treat severe pain, often in patients recovering from surgery or those with chronic pain conditions. It is much stronger than morphine, making it effective in small doses. However, because of its potency, fentanyl can be very dangerous if misused or taken without medical supervision. In recent years, fentanyl has become a significant concern in the context of the opioid crisis in many countries. Illegally manufactured fentanyl is often mixed with other drugs, leading to a higher risk of overdose. Awareness and education about the dangers of fentanyl are crucial for preventing misuse and saving lives.
