Drug addiction

Drug addiction refers to the addiction to addiction. With long-term use of drugs, drugs occupy the receptors and inhibit the synthesis of endogenous morphine-like substances. Once discontinued, endorphin deficiency is easily present and withdrawal syndrome appears. Drugs are addictive narcotics and psychotropic substances such as opium (opiates), heroin, cannabis and cocaine. They do not include addictive substances in tobacco, alcohol, tranquilizers, sleeping pills and other stimulants and analgesics. Opioids are made by drying the emulsion exuding from the immature capsule of the papaver family plant Poppy, and containing a variety of alkaloids with similar effects such as morphine, codeine, ethylmorphine, and heroin. In 1973, it was confirmed that there are opioid receptors in the central nervous system, and morphine-like substances (endorphins) can also be produced in the body. The analgesic effect of this class of poisons is related to the opioid receptors acting on the gray matter around the thalamus, ventricles, aqueducts, and glial regions of the spinal cord; elimination of emotional changes caused by pain is related to the limbic system; causing euphoria seems to be related to blue spots Opioid receptor binding is involved. The central nervous system also has sedation, hypnosis, inhibition of breathing, antitussive, and vomiting (stimulative chemoreceptive zone of the medulla oblongata); it can also contract biliary smooth muscle and Oudi sphincter and increase biliary pressure; increase ureter smooth muscle tension and contract bladder sphincter Causes dysuria; contractes bronchial smooth muscle. It has an inhibitory effect on the cardiovascular system, causing slow heart rate and orthostatic hypotension. Slow bowel movements cause constipation. At common doses, nausea, vomiting, constipation, sweating, ureteric and bile duct spasms, etc. may occur, as well as dry mouth, bradycardia, palpitations, and dilated pupils. Large doses can produce respiratory depression, hypotension, heart failure, and deep coma. Coma during acute poisoning, depression of breathing depth, extreme reduction of pupils, decreased blood pressure, cyanosis, decreased body temperature, wet and cold skin, severe death from respiratory paralysis. Addiction (withdrawal syndrome) Generally, people take drugs 3 to 4 times, or even 1 to 2 times, to become addicted. When I first took drugs, I felt uncomfortable and even very uncomfortable. I had dizziness, nausea, vomiting, and upset symptoms, but many people changed from uncomfortable to euphoric in a short period of time. They were active and energetic. The first drug abuse will also cause sweating, redness of the eyes, and even a decrease in blood pressure, pinpoint reduction of the pupils, needle-like shape and refractory constipation. It may also affect ejaculation, menstruation and ventilation. Once addicted, strong physical and psychological dependence can occur. Physiologically, stopping the drug will feel unwell, yawn, tears, runny nose, cold sweat, and then become weak, unable to get up, lose appetite, and may be accompanied by nausea, vomiting, diarrhea, etc. When the inhibitory effect of drugs on the central nervous system turns to excitement, the pupils dilate, the heartbeat speeds up, blood pressure rises, muscles tremble, and twitching. In severe cases, delirium, dehydration, electrolyte imbalance, and extreme collapse occur. Psychologically, drug users have a constant and cyclical desire for drugs. This desire is overwhelming. Once the drug is interrupted, it can produce the so-called hell-like painful withdrawal symptoms, become extremely selfish, and obtain drugs without any means. It has nothing to do with society and the family. Responsibility, forgetting honor and shame, endangering individuals, families and society.
