Which of the following is an opiate narcotic?

Explanation

Opiates are derived from opium along with their synthetic relatives. Opiates have narcotic, analgesic, sedative, and astringent effects. A narcotic is a drug that induces stupor and relieves pain. Morphine is the main opium alkaloid, which is a strong analgesic and also has a sedative and calming effect. It depresses the respiratory center and contributes to the fall in blood pressure. It can cause the release of ADH, reduction in urine output, constipation, and mild hyperglycemia, among other effects. It also leads to addiction.Barbiturates are substituted derivatives of barbituric acid. They reduce anxiety and induce sleep. Amphetamines are synthetic drugs that act as strong stimulants. LSD (Lysergic acid diethylamide) is one of the most powerful hallucinogens, causing severe damage to the central nervous system.
