First, with so many recent headlines about celebrity drug use, doctor, what do you think? There will be too much unfairness in this world, but there are two things that need to be upheld as absolutely fair: one is the law and the other is medicine. Therefore celebrity drug use is no different from fan drug use, they are both human beings. As for individual differences, I feel they are more likely to be targeted by drug dealers, coupled with good financial conditions and a prevalent culture in the industry, so what we see may just be the tip of the iceberg, and once you’re in the trap, it’s not easy to get out of it. The drug thing is even more so, Whitney Houston, Cory Monteith are my favorite stars, and both ended up dead. It’s a pity. Second, what is the relationship between drugs and medicines? Drugs in English is DRUG, many drugs are drugs, such as ketamine, morphine, dulcolax, ephedrine, or originally developed as a drug, like the infamous heroin. Recently the United States has also been looking into how to legalize the medical use of marijuana, as they have a very high medical value, treating many conditions such as depression, chronic pain, and whatnot. Constipation medicine, and we usually eat cold medicine, cough syrup, are excellent source of raw materials in the hands of drug traffickers, and now a lot of time to buy drugs to register ID card is the reason. What do they smoke? There are too many kinds of drugs, different countries and cities have great differences. According to the different generations and different synthesis methods, we generally divide drugs into traditional drugs and new drugs. At present, young people are mainly affected by new drugs. Not long ago, some scholars at home and abroad thought of a very good way, they sampled and analyzed the domestic sewage of several big cities in China, and found that the popular application of drugs in China is not quite the same as in Europe and the United States, and the abuse of methamphetamine and ketamine is the most. Geographically, Shenzhen and Guangzhou have higher rates of drug abuse than Beijing and Shanghai, and these results are very much in line with drug trend projections from the United Nations Office on Drugs and Crime. The drugs used by these stars are either marijuana, ketamine (ketamine) or methamphetamine. Fourth, are there a lot of drug users? More than you might think. One is more, the other is smaller. Ke Zhendong 23, Fang Zunming 32, Li Daimo 26, Zhang Mo 32 …… are considered small fresh meat at least insurance meat. The actual drug abuse population in the proportion of young people is getting bigger and bigger, in these years I hand most of the patients are after the nineties. This year our country registered 2.58 million drug addicts, because the actual people must be more than this, according to the international practice of 1:5 calculation, the actual roughly tens of millions of people in the drug, that is, according to the national population average up, 150 people may have a drug addict. Comrade reporter, do you say more? Fifth, the new drugs on the body harm? Don’t believe in all that nonsense, such as new drugs are not addictive and harmless. Once you get in, you can’t get out. Mental symptoms such as depression, violence, suicide are very common symptoms, while the physical symptoms of these teenagers and their families suffer a lot. As a urologist, I have been concerned in recent years about drug-induced urologic injuries. Ketamine-induced urological damage can cause very serious lower urinary tract symptoms, including urinary frequency, urgency, urinary pain, hematuria, which in turn causes bladder contracture, kidney failure, and even bladder cancer, and not a few untreated deaths are eventually caused; marijuana causes bladder cancer, prostate cancer, and non-seminomatous germ cell tumors. Injection of heroin and cocaine can cause Fournier’s gangrene, abuse of cough syrup can cause ephedrine as the main ingredient of the stones …… too much, the key is that they are still very young, so the future, the family are buried.

Anything that is pleasurable can lead to addiction. The reasons are complex, but there is one principle that everyone understands: the reward mechanism. The Chinese are familiar with Pavlov’s dog every time. It’s the same with drugs. The brain has a complex reward system, but the reward is not money, but dopamine, opioid peptides, C-aminobutyric acid and other chemicals that make people happy. Normally, when someone calls you “handsome” or gives you “likes” in the circle of friends, these happy substances are released; under the effect of drugs, the release dose of happy substances will be multiplied indefinitely, so that people feel “twice as good! “, “that is not a thing”…… hey, is that you drink drink HIGH to sing K feeling amplified dozens of times hundreds of times. Over time, do not rely on the stimulation of drugs, these happy substances in the normal state will not be released at all, so long-term drug addicts usually stagnant face, slow thinking, pain, after the use of drugs to enter the world of bliss. Figure: There is a reward pathway in the brain, the main structures include: amygdala (amygdala), hippocampus (hippocampus), ventral tegmental area (ventral tegmental area), nucleus accumbens (nucleus accumbens) and prefrontal cortex (prefrontal cortex).
