Opioids
Opioids are a class of drugs that are commonly used for pain relief. They act on the opioid receptors in the brain, spinal cord, and other parts of the body to produce pain relief and feelings of euphoria. While opioids can be effective for managing severe pain, they also carry a high risk of addiction and dependence. In recent years, there has been increasing concern about the misuse and abuse of opioids in the sports community. However, opioids are not the correct answer to this question.

Barbiturates
Barbiturates are a class of drugs that act as central nervous system depressants, producing a wide range of effects from mild sedation to deep anesthesia. They were once commonly used for the treatment of anxiety, insomnia, and seizures, but their use has declined due to the development of safer and more effective alternatives. Barbiturates are highly addictive and can cause severe withdrawal symptoms, making them dangerous for misuse. However, barbiturates are not the correct answer to this question.

Cannabinoids
Cannabinoids are a group of compounds that act on the cannabinoid receptors in the brain and other parts of the body. The most well-known cannabinoid is delta-9-tetrahydrocannabinol (THC), which is responsible for the psychoactive effects of cannabis. While cannabis is still illegal in many parts of the world, there has been a growing acceptance of its use for medical purposes. Some sportspersons may be using cannabinoids, particularly CBD (cannabidiol), for its potential benefits in managing pain, inflammation, and anxiety. However, the excessive use of cannabinoids by sportspersons is not supported by scientific evidence and is against the rules of many sports organizations. Therefore, cannabinoids are the correct answer to this question.

Lysergic acid diethylamides (LSD)
LSD is a powerful hallucinogenic drug that produces altered perceptions of reality and an expanded state of consciousness. It is not commonly used by sportspersons and does not provide any performance-enhancing effects. Therefore, LSD is not the correct answer to this question.

In conclusion, the drug that is being excessively taken by some sportspersons nowadays is cannabinoids. While there may be some legitimate medical uses for cannabinoids, the excessive use of these substances by sportspersons is not supported and is against the rules of many sports organizations. It is important for sportspersons to prioritize their health and well-being and to adhere to the regulations set forth by their respective sports governing bodies.
