Document Summary
Narcotic - reduce pain and induce sleep and euphoria by mirroring opiates in the brain (endorphins, etc. ) Depressants are a group of drugs that decrease central nervous system activity. The primary effect is to reduce our levels of physiological arousal and help us relax. Included in this group are alcohol and sedative, hypnotic, and anxiolytic drugs, such as those prescribed for insomnia. Stimulants, the most commonly consumed psychoactive drugs, include caffeine (in coffee, chocolate, and many soft drinks), nicotine (in tobacco products such as cigarettes), amphetamines, and cocaine. In contrast to the depressant drugs, stimulants make us more alert and energetic. Opiates include opium, morphine, codeine, and heroin; they have a narcotic effect - relieving pain and inducing sleep. Hallucinogens essentially change the way the user perceives the world. Sight, sound, feelings, and even smell are distorted, sometimes in dramatic ways, in a person under the influence of drugs such as cannabis and lsd.
