Compared with traditional drugs, new synthetic drugs may show some different characteristics in some aspects, but they cannot simply be said to have an absolutely stronger single effect, but there are many complex differences.： **Physiological response** -**Excitement level**： -**Synthetic drugs**: Such as meth, etc., can often bring a strong sense of excitement, causing the user's heartbeat to speed up, blood pressure to rise, and high mental excitement, which may last for several hours or more, far exceeding the general excitement caused by traditional drugs such as opium and heroin. The level of excitement. -**Traditional drugs**: Taking heroin as an example, there will be a brief euphoria in the early stage, followed by a state of relaxation and tranquility. The degree of excitement is usually not as strong and lasting as synthetic drugs. -**Hallucinogenic effect**： -**Synthetic drugs**: For example, ecstasy, K powder, etc., the hallucinogenic effect is more prominent. Users may experience distortion of perception, auditory hallucinations, visual hallucinations, physical weightlessness, spatial perception disorders, etc., which can make people enter a fantasy but extremely chaotic mental state out of reality. The depth and breadth of this hallucinogenic experience sometimes exceeds that of traditional drugs. -**Traditional drugs**: Like cannabis, they have certain hallucinogenic effects, but compared with the hallucinogenic effects of synthetic drugs, their performance in terms of distortion of perception is not so extreme. **Psychological dependence** -**Synthetic drugs**: The addiction mechanism is complex and rapid, and it can easily cause strong psychological dependence in a short period of time. Users are extremely eager for the kind of detachment from reality, extreme excitement or hallucinogenic feelings it brings. Once they stop using it, they will quickly experience strong withdrawal reactions, such as anxiety, depression, irritability, strong craving, etc., Psychological dependence may be very strong after several uses. -**Traditional drugs**: Psychological dependence is also formed faster, but in some ways, the urgency and intensity of psychological dependence caused by synthetic drugs may be more prominent. Traditional drug users will become dependent on the euphoric and escapist effects of drugs, but the psychological addiction caused by synthetic drugs is often accompanied by a stronger pursuit of specific spiritual experiences. **Damage to the body** -**Synthetic drugs**: Damage to the cardiovascular system and nervous system is huge and rapid. Long-term use can lead to serious heart problems such as arrhythmia and myocardial infarction, cause mental disorders such as schizophrenia and paranoia, and may also cause irreversible damage such as memory loss and cognitive dysfunction. The development of these damages is sometimes very rapid, and obvious symptoms may appear within a relatively short period of use. -**Traditional drugs**: Mainly damage the functions of various organs of the body, such as chronic damage to the respiratory system, digestive system, immune system, etc., resulting in respiratory depression, loss of appetite, decreased immunity, etc. In contrast, the acute and severe cardiovascular and nervous system damage caused by synthetic drugs is more prominent in some cases, and it is often not easy to detect at an early stage, and once the problem occurs, it may be more serious.
