Basic human rights are the funding of every democracy. Take for example the right to not be discriminated, the right to travel freely and that everyone is innocent until the prove is there to be prosecuted. However, in a democracy there are also rules to follow. The police and other government authorities have the right to test you on the use of cannabis.
The choice to smoke often leads to discrimination and prosecution. Especially, no-one can participate in the traffic when smoking cannabis. Although cannabis is legalized by most authorities, and even more important by the politicians, the average cannabis smoker will have to face to consequences when they leave their home. So who would want to test you for cannabis use? Most companies ask their applicants to do a drugs test. It is not really clear why they do this. There are of course some jobs that are not the right fit for frequent cannabis users; like truck drivers. However, THC could also influence the job of lawyers, judges and business men? We do not know.
A scenario which is most common and were you should take a drugs test is when you are driving a motor vehicle on public road. Most tests are done via a salvia test. When you make sure you drink enough; this test can be manipulated. Because the salvia will have enough THC from smoking; make sure you always wait 1 hour and drink at least 2 glasses of water when you hit the road. The test can be manipulated this way, but we cannot provide a 100% security for this. Another great way to avoid this is a space cake or weed cake. If you eat the cake your salvia will not contain THC when you drink just one glass of water. We’re the alcohol tests are becoming better and better, the THC tests are still primary and did not develop as well as the alcohol tests.
