The External Character of Heroin First, drugs are divided into opioids and synthetics. Opioids are poppy extracts, alkaloids and in vitro derivatives. Their production relies solely on the opium poppy, also known as the traditional class of drugs. Heroin is arguably the most widely abused drug in the world. Also known as number four, white crystalline powder, long well, and the appearance of your ordinary high gluten flour low gluten flour looks similar, but its harmful effects than nitrogen dioxide poisoning. Heroin is one of the most important drugs banned in China, and is extremely harmful to human physical and mental health. Long-term use and injection of heroin can cause personality disintegration, psychopathy and life expectancy reduction, especially for the nervous system damage is most obvious. It should be noted that due to the addictive nature of heroin, there is no effective way to quit, and the rate of relapse is extremely high. Once addicted, the possibility of relying on one’s own willpower to lift the addiction is slim. The effect of the “mind addiction”. The next thing we’ll talk about is the “king” of methamphetamine, also known as methamphetamine, which is pure white crystals and crystal clear, so it’s called “ice” by most drug addicts. Generally speaking, the higher the purity the more transparent the color, currently some drug dealers on the black market often for profiteering, will be mixed with other substances in the drug, so there are many differences in color. The methamphetamine toxicity is very strong, small doses will have a short-lived euphoric anti-fatigue effect, so people in the drug circle is called “Power Pill”, but once addicted, the harm is irreversible, serious damage to the nervous system, which is the most intuitive manifestation of the addict hallucinations, delusions and violent tendencies. The most important thing to remember is that most of the addicts who fall into drug addiction are initially exposed to drugs because they were brought to the “wrong path” by their so-called friends, and many of them even think, “I’ll just smoke once to satisfy my curiosity, next time I won’t smoke on the line. It is this ignorance that causes the source of a tragedy. Here we explain from a neuropharmacological perspective why addiction is so hard to quit! “First of all, when you take drugs, your body develops a resistance to the external drug (in fact, the body adapts or changes accordingly to most external environmental changes). For example, when you take heroin, your nervous system is stimulated by the drug in a way that makes you feel extremely pleasurable, but this stimulation is excessive, so the body develops an opposite mechanism that causes some pain to the body and counteracts the excessive pleasurable stimulation. To make matters worse, this resistance response is acquired through conditioned reflexes that are easily triggered, such as seeing a “drug buddy,” seeing a syringe, or simply sitting in the same place where the drug was originally used, can trigger the conditioned firing. When the conditioned reflex occurs, the body will spontaneously generate a “resistance response” that causes you great pain and produces various physiological reactions that force you to use drugs to alleviate the pain. This is why many people who have “successfully recovered” from drugs quickly return to drugs when they return to familiar surroundings. This is also known as “mind addiction” and it is difficult to quit. If you want to use your willpower to challenge the science of physiology, it is almost impossible. So is there any medical treatment for addiction? The answer is yes, many addicts have tried forced detoxification in rehab or even buried drugs, but the relapse rate is just as high, so how can relapse be minimized? It seems that the only way to avoid relapse is through minimally invasive stereotactic surgery. When weighing the pros and cons, for the addict, surgical detoxification may not be the last straw that helps to save your life from drugs.
