Can drug dogs smell vapes?

Yes, police dogs can detect the smell of e-cigarettes. However, whether they will react to it entirely depends on what they have been trained to find.

Amazing olfactory ability: Dogs' sense of smell is much stronger than that of humans. Therefore, regardless of whether the e-cigarettes contain nicotine oil, THC (tetrahydrocannabinol) oil, or other substances, they can all detect them.

The key lies in the "training target": Police dogs will only alert when they are exposed to the specific scents they have been specially trained to detect.

Ordinary drug-sniffing dogs: The vast majority of police dogs are trained to find illegal drugs (such as cocaine, heroin, methamphetamine, etc.). Nicotine is legal, so they usually are not trained to recognize nicotine and do not react even if they smell it.

Specialized "e-cigarette detection dogs": In recent years, to address the issue of e-cigarettes in schools, specialized police dogs have been trained for this purpose. They are specifically trained to detect the smell of nicotine and THC oil. Police dogs in places like the UK have also been trained to search for illegal e-cigarettes and tobacco.

Special note on THC (marijuana) e-cigarettes: If an e-cigarette contains THC (marijuana extract), any drug-sniffing police dog that has received training will likely alert to it. However, a legal complication is that police dogs cannot distinguish between legal industrial hemp (Hemp) and illegal marijuana (Marijuana) because their smells are very similar.

So, in simple terms: Police dogs can detect all e-cigarettes, but only the specially trained ones will alert to nicotine e-cigarettes; while THC-containing e-cigarettes may be detected by any drug-sniffing dog.
