no listen to this, ok i went to a military school for a couple years, and they would constantly bring in sniff dogs to smell for pot weed drugs weapons, ect. What we used to do was take crayola markers (the thicker ones) took out the entire center of it but were sure to leave the tip in. (we found the markers to still be functional for a while lol) then we filled the middle with weed tobacco, anything that would fit and needed hiding. There was akid from ohio who hunted and he sprayed that hunting shit thats supposed to distract scent. well it worked everytime. and we used a whole box and each person had their own color (mine was green) those were the good days.
