Your firecrackers should not smell as long as the foil is air tight. If you use only enough foil to cover the cracker once (or what have you) then you might notice a faded smell of bud. To the untrained nose it wont really reek, but those who smoke weed will probably recognize the smell (who doesn't these days anyway?).

My recommendation is 2-3 full wraps of foil around your cracker, so the chance of it smelling is unlikely. Also, I found taquitos to be a great masking agent, lol. Throw 2-3 in there along with your crackers and the only thing you'll be smelling is chicken or beef. The Taquitos come out undercooked, however.
