Do you usually smoke before driving? Attention, companies are developing a "breathalyzer" to detect cannabis through breath

Omega Laboratories, a leading drug testing lab, and Cannabix Technologies announced the development and validation of a cannabis breathalyzer test. The integration of this new technology allows for rapid and accurate detection of tetrahydrocannabinol (THC) levels in breath samples.

This new approach simplifies the testing process and ensures reliable results for clients in various sectors, such as law enforcement, workplace safety, and healthcare.

Toxicological Examination in Brazil

In Brazil, the Toxicological Examination with a long detection window is mandatory for drivers in categories C, D, or E (CNH). This examination analyzes samples of hair, body hair, or nails and checks for the use of psychoactive substances with a minimum retrospective analysis of 90 days, according to federal law No. 13,103 of March 2, 2015.

Collaboration between companies validates products

Cannabix and Omega collaborated to optimize the design of the Cannabix BCU and the compact breath cartridge technology. The BCU includes an air flow self-check, environmental sample collection to rule out external contamination, and a connected breath cartridge to simultaneously collect two samples (A and B).

Omega is incorporating the breathalyzer test into its service portfolio, and extensive research supports the technology. A comprehensive validation study will be published to demonstrate the system's effectiveness in real-world scenarios.

The validation includes a method to simultaneously quantify Δ-9-tetrahydrocannabinol, Δ-8-THC, cannabidiol (CBD), and cannabinol (CBN) in aerosols protected against the Cannabix Technologies Breath Collection Unit (BCU).

All breath samples validated by Omega undergo a testing process using mass spectrometry, considered the gold standard in analytical chemistry.

Effects of cannabis on the central nervous system

THC, the main psychoactive component of cannabis, mimics natural neurotransmitters and alters communication between neurons. It binds to cannabinoid receptors in areas related to pleasure, memory, thought, and scientific inquiry.

The immediate effects range from changes in sensory perception to difficulties in performing complex tasks. At high doses, THC can even induce acute psychosis. Long-term use, especially when consumed during adolescence, can cause structural changes in the brain, affecting memory and cognitive skills.

The mode and frequency of consumption directly influence the effects of cannabis on the nervous system. Early use, during adolescence, increases risks due to the vulnerability of the developing brain.

How to detox from THC

Detoxification refers to the removal of toxic substances from the body. In the case of THC, it is safer to allow it to be naturally eliminated from the body, as there are no medications that speed up this process, unlike substances such as cocaine or heroin.

The psychoactive effects of THC last on average two hours, but the compound can remain in the body for up to 30 days or more, making complete detoxification difficult. Vigorous exercise may release stored THC from fat tissue, but does not significantly speed up the detoxification process.

Individuals with a lower body fat percentage may store less THC, but the cannabinoid can be present in the blood or urine for long periods, especially in frequent users.
