The information provided below is only for background information on reducing accidental injuries. It does not constitute encouragement or recommendation of any illegal behavior, nor is it a substitute for professional medical or psychological counseling. Cocaine use itself has inherent risks, and even if measures are taken, the risks cannot be completely eliminated. If you or someone you know is facing drug problems, it is recommended to seek professional help (such as a doctor, drug rehabilitation expert or psychological counselor). The following are some common suggestions for reducing risks. Please note that these suggestions cannot guarantee "safety": 1. Never mix other substances • When cocaine is mixed with alcohol, sedatives or other drugs, it may cause unpredictable interactions and serious risks. • Avoid using other substances that may increase the burden on the cardiovascular and nervous systems at the same time. 2. Test the source and ingredients of the drug • Cocaine on the market is often adulterated with other substances. If conditions permit, you can use drug testing tools (such as test kits) to test the purity and possible adulterants before use, but this is not 100% accurate. • Understand that even if the test passes, it cannot completely guarantee that the drug risk is minimized. 3. Pay attention to dosage and frequency • Understand your tolerance, start with a low dose, and avoid overdose, as well as overstimulation or other health risks due to unknown dosage. • Try to avoid frequent use, as cumulative use may cause long-term damage to cardiovascular, neurological and mental health. 4. Choose a safe environment • Use in a familiar and relatively safe environment, preferably with a trusted, sober friend to supervise, so that quick action can be taken in the event of an accident. • Avoid using in crowded places or where help cannot be obtained quickly. 5. Understand your health status • If you have a history of cardiovascular disease, high blood pressure, mental illness or other health problems, using cocaine will have additional risks. • For people whose health status is unclear, any use is an increased risk behavior. 6. Keep in mind the impact of the route of use • Different routes of use (smoking, snorting, injection, etc.) have different risks. For example, the risks of injection include infection and transmission of diseases; snorting may damage the nasal mucosa. • Try to understand the health risks of each route as much as possible and choose a route with relatively lower risks (note: this is not a risk-free choice). 7. Reflection and Self-Assessment • Reflect on your use behavior frequently and pay attention to whether you have developed dependence on the drug. • If you find it difficult to control the frequency or dosage of use, please seek professional drug rehabilitation or psychological counseling as soon as possible. 8. Understand first aid measures • Understand the initial response methods for poisoning, arrhythmia or other emergencies, and seek medical help immediately. • If there are friends around who can provide first aid knowledge, you can also pay attention to risk signals during use. Once again, all of these measures are only to reduce some potential risks, but there is no way to make cocaine use completely safe. If you have a choice, the safest option is to avoid using these substances that have serious health and legal risks. If you are experiencing related distress, you may wish to contact local medical professionals or drug rehabilitation support agencies for help.
