Marijuana is the easiest drug to test for. The metabolites (READ: the byproduct of use, not the active chemical that gets you high) can stay in your system for up to 90 days in chronic use cases. While heroin is out in 4. Alcohol is out in 2. So if anything, Marijuana is the easiest drug to enforce.

That said, I don't want to continue feeding the troll, or the chronically misinformed.

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.
