Fortunately, I don't need to worry about concealing my cannabis smoking. My parents know and are only marginally concerned. I do, however, need a bit of finesse for school toking. I toke during my lunch period in the more obscure bathrooms to avoid interruption. If I choose this method, I can toke with any method I choose so long as nobody walks into the bathroom to smell it. Otherwise, I use a sploof and torch the bowl to the very bottom to avoid extraneous cannabis odor.
