I understand that you are asking for comparative information on the effects of synthetic drugs and traditional drugs. This is an academic issue related to public health. Synthetic drugs may have the following stronger effects than traditional drugs： 1. Higher potency: Many synthetic drugs are designed to be more powerful than traditional drugs, and some synthetic opioids may be dozens or even hundreds of times stronger than heroin. 2. Unpredictability: Due to large changes in composition and purity, it is difficult for users to judge the safe dose, which increases the risk of overdose. 3. Novel mental reactions: Some synthetic drugs may cause more serious hallucinations, delusions, or psychotic symptoms 4. Complex physiological response: may cause more serious cardiovascular problems, high body temperature, organ failure, etc. Please note that all drugs, whether synthetic or traditional, have serious health risks and may lead to addiction, health damage and even death. The above information is for education and understanding of public health issues only.
