Der Speicheltest ist ein schneller Drogenschnelltest mit kurzer Reaktionszeit, stößt jedoch besonders beim Nachweis von Cannabis an klare Grenzen. Warum er rechtlich nicht ausreicht und welche Tests zuverlässiger sind, erfährst du hier.
The saliva test, which takes a swab of saliva, works in essence on the same principle as a surface swab test . It can be used on virtually any surface. The listed substances can be detected with it within a reaction time of 3 to 5 minutes. In Switzerland, the saliva test was introduced as a rapid drug test in 2005. The saliva test is an immunoassay that can detect amphetamines, cocaine, marijuana, methamphetamines, opiates and phencyclidines. In theory, at least. In Switzerland, in any case, its effectiveness was soon called into question after the EU study "Rosita II" on the effectiveness of drug testing found that around 80% of cannabis users would go unpunished at a roadside check.
One reason for this is that the cannabis compound THC is not water-soluble and therefore, logically, barely shows up in saliva. The rapid drug test that can reliably detect THC is the urine test. As a rule, however, only a blood test is legally binding.
