It is very inaccurate and dangerous to judge whether a drug is doped by observing the color or smell, and you must never try it yourself. Drugs are extremely harmful, and their identification requires professional laboratory equipment, technology and professionals. Relying on subjective judgments such as color and odor is neither reliable nor scientific, and may also face serious legal consequences and health risks due to misjudgment. If suspected drug items are found, they must be immediately reported to the public security organs and other relevant law enforcement departments, and strictly identified and dealt with by professional institutions and personnel. They must not rely on non-professional means to judge without authorization, so as not to endanger one's own safety and lead to illegal and criminal acts.
