well brrg744 i've been caught many times by parents teachers, even my team leader in the army, one thing that may help go for a walk when you smoke a joint or find a spot bout a block from home or so and go there, smoke then go back home. as for the roaches try swallowing them or just flick em out when you're done with em. swallowing roaches does taste like shit but it'll give you a mellow addition to your high.
