How To Pass A Saliva Drug Test

The cannabis legalization movement has been gaining strength across the country and has resulted in marijuana being legalized in multiple states for recreational use. With the change in legal status, the number of pot lovers has also risen significantly.

However, tolerance for weed smokers has not increased among employers or law enforcement officers. In many states and workplaces, mandatory drug tests can be administered without notice.

Not to mention, driving under the influence of any drug is still illegal and punishable by law. Employer drug testing falls under federal law, which still recognizes marijuana as a Schedule I substance.

The legalization of marijuana has increased the frequency of federal and employer drug tests. Traditional urine tests are slow and costly, with results normally available a few days later. The popularity of the mouth swab drug test is due to its accuracy. 

Quick and cheap saliva drug tests are the new trend in marijuana detection. Luckily, there are a few simple methods to successfully work out how to pass.
