To start it off, let us be the first ones to tell you that smoking is a self-harming activity that immediately causes lung cancer and other lung-related medical issues.
There have been big banners and advertisement corners and digital advertising about smoking and its serious effects on human health.
This brings us to the necessary dealings with drug tests including a smoke screen which is used to let the doctors know if the patient has been smoking or not.
Any kind of intentionally inhaled smoke will give a positive result in the smoke test, which would mean that the patient has indeed been smoking in the immediate past.
However, what people argue to be a gray area in the smoke screen is the presence of second-hand smoke or smoke which is unintentionally inhaled by the patient. Probably by being near people who have been smoking drugs.
Experts, including researchers and scientists, claim that it is proven that secondhand smoke actually does contain the psychedelic substance THC or delta-9-tetrahydrocannabinol which is present in marijuana or commonly called, “weed”.
The Centres for Disease Control and Prevention have amply verified this reality.
Hence, the proving of this fact has raised the criticism and concerns of almost everyone. The most important question they have is, “Does inhaling this secondhand smoke cause you to get a false positive on the smoke screen?” They have found out through the uncountable tests they have run on patients, that this secondhand smoke does not actually cause a positive result in the smoke screen.
Even though there are supposed to be traces of THC in the person inhaling the secondhand smoke, a smoke screen does not bring them to light.
The fact is, smoking will eventually lead to lung-related medical issues, most possibly lung cancer, which does not really have a specific proven cure yet and cancer might very well spread to other regions of the body, like the kidneys, the liver, the prostate, and so on.
Thus, avoiding activities that involve smoking would be the most sensible and secure course of action. People assert, however, that it is difficult to do so because substances like tobacco and marijuana offer a world of hallucinogenic pleasure that is difficult to resist.
Despite the answers and assurance of the scientists and doctors, people are still on the fence about this.
They believe that at one point, this secondhand smoke might cause a false positive and disrupt the whole smoke screen. And since it is not possible to stay away from secondhand smoke, it is still a gray area for many of the population.
