How do you disguise the smell of smoke?

I have plenty of experience with this, just to preface this. The number one best thing to mask the smell with is dryer sheets, the kind people put in their dryers to make their laundry softer and fresh smelling. Rub one over your clothes and the smell will be gone in a jiffy. Reason why this is the best method (I know it sounds totally random) is the dryer sheets don’t smell like anything on their own. And they don’t actually MASK the smell, they pull it off the clothing entirely.
If you don’t want to go out and buy dryer sheets and your parents don’t have any at the house, there’s always the option of doing decent physical activity before going home. If you really aren’t smoking, and aren’t around them too much when your friend’s smoke, then running or doing anything else that make your body heat up and sweat will get rid of the smell pretty well too. If you sat around them when they smoked, forget it, because it’ll be on your skin and running will make it worse. There’s also always febreeze, or other canned air freshners, but they usually have a smell of their own. If you’re parents notice it and pick up that your covering something, that could be worse than if they smell the smoke on you, because then they know you were trying to hide it too.
Good luck!
