Buy synthetic urine if you want to be safe for sure. Usually military and probation drugs tests are the only tests that they check you out while you piss. So for most jobs you just go to the bathroom alone (usually at a designated testing center). The main thing you have to worry about synthetic urine is keeping it at a temp or 96-98 or so but they include warmers to wrap around the bottle after heating it up in microwave for a few secs.

As for the question in op... No I don't support only making weed legal. I support making all drugs legal. It is the only thing that would ruin the Mexican drug cartels. If all drugs were legal then they would have to find another illegal operation or legally manufacture the drugs.
