How Does a Marijuana Breathalyzer Detect THC?
A marijuana breathalyzer, also known as a THC breathalyzer, is designed to detect the presence of THC in a person's breath. THC, or delta-9-tetrahydrocannabinol, is the primary psychoactive compound in cannabis.
Principle of Operation
Marijuana breathalyzers work on the principle of detecting THC in the breath, which is a result of the drug being metabolized and excreted through the lungs. These devices use a chemical sensor that reacts with THC molecules.
