How do I hide the smell of smoke in my bathroom?

I got caught smoking bud in my bathroom because the smell was lingering and I tried to hide the smell the best I can but I'm not a good judge of smell after I smoke because everything there after will smell like smoke to me so I can't tell if it's gone, and the bathroom is the only place where I can smoke and nobody will see me. A method I think might work is to inhale the smoke then exhale it into a ballon, and when I'm finished I close the ballon then take it outside, will that work????
