Drug-detection dogs, as specially trained dogs, can obey the instructions of the drug-detection dog handler, search different luggage items in various places, and find objects hidden with drugs. Their main job is to detect drugs through their sense of smell and help the police in anti-drug operations.

Drug addiction refers to the habit of drug addiction, with characteristics such as physical dependence and mental dependence. The main reasons for addiction are the reward effect of drugs and the withdrawal symptoms. Although drug detection dogs are often exposed to drugs, due to the nature of their work and training methods, they themselves will not develop an addictive reaction to drugs. This is because drug detection dogs only use their sense of smell to detect drugs, rather than ingesting or snorting drugs.

Therefore, drug detection dogs will not become addicted to drugs. They work for mankind with the characteristics of economical, fast, efficient and accurate drug detection, and have become a powerful weapon for drug detection and drug control by public security, customs, border defense and other departments.
