First of all, I understand your concern about this issue very well. Drugs themselves are already very dangerous, and drugs doped with other substances may pose greater risks. Therefore, it is very important to understand how to identify whether drugs are doped. ### Judge by color 1. **Abnormal color**: Different types of drugs usually have their own specific colors. For example, pure cocaine is usually a white powder, while heroin may be white, brown, or gray. If you find that the color of the drug does not match expectations, or the color is uneven, it may mean that it is doped with other substances. 2. **Color spots**: If there are obvious color spots or uneven color distribution on the surface of the drug, this may be a sign of doping. ### Judge by smell 1. **Abnormal smell**: Some drugs have a specific smell. For example, cannabis has a unique smell, while cocaine may have a slight chemical smell. If you smell an unusual, pungent, or chemical smell, it may mean that the drug is doped with other substances. 2. **Odorless**: If a certain drug usually smells, but you can't smell anything, this may also be a sign of doping. ### Other precautions 1. **Texture changes**: The texture of drugs may also change due to doping. For example, powdered drugs may become agglomerated or viscous. 2. **Use test tools**: If you suspect that a drug is doped, the safest way is to use a special test tool or kit to detect its composition. These tools can help you more accurately identify whether drugs contain other substances. ### Important reminder -**Don't try**: If you suspect that drugs are doped, the safest thing to do is **Don't use it**. Doped substances can be very dangerous and even fatal. -**Ask for help**: If you or someone you know is struggling with a drug problem, please seek professional help immediately.
