Well, even with only 2 or so drug searches a year, you would be far better served if you had rolled a joint and tossed the roach or just smoked at home before going to school.

You were extremely lucky to not get busted. You also should accept responsibility for using illegal drugs and should not be surprised if you're arrested when you bring them to school or public places.

You could have prevented this situation from the very beginning by not having drug paraphenalia and scales and visine in the car, but that sucks they messed up the exterior of your vehicle.

Its just a matter of time for you to get arrested if you dont be careful man.

Be Safe!
