You reiterate the point. It stays in the system longer.

Also, length of time and ease of test is not the same. Breathalyzer's are under $5 to produce and use just breath. No test for THC exists that doesn't require a more substantial "contribution" to the test. (hair, urine, blood)

Drug tests look for 11-nor-9-Carboxy-THC, not Tetrahydrocannabinol. The amount in your system days after use is so minimal so that it has no effect. I'd like to see a case study of someone getting measurably impaired days after use.
