The harm of drugs
First, the mechanism of drug harm to human body

Strong dependence caused by repeated medication.
Physical dependence: drugs act on the human body, making the human body adapt to changes and forming a new equilibrium state under the action of drugs. Once the drug is stopped, the physiological function will be disordered and a series of serious reactions will occur. This is the so-called withdrawal reaction, which makes people feel very painful. In order to avoid withdrawal reaction, drug addicts must take drugs regularly and constantly increase the dose, so that drug addicts can not live without drugs all day.
2. Mental dependence
After drugs enter the human body, they act on the human nervous system, which makes drug addicts have a strong desire to take drugs and drives them to desperately seek and use drugs. Once mental dependence occurs, even after detoxification treatment, it often takes months or even years to fully restore the original physiological function after the withdrawal reaction in the acute stage is basically controlled.

Once heroin is stopped, they will have symptoms such as anxiety, cold and hot, goose bumps, tears, runny nose, sweating, nausea, vomiting, abdominal pain and diarrhea. The pain of this withdrawal reaction in turn urges drug addicts to do everything possible to maintain drug use in order to avoid this pain.
