I have been able to no react to this issue for a long time, I even use blankets from my parents with thirdhand smoke on them. But not I am all of a sudden freaking out and want to wash all my bed linen (will be very pricey) I know studies do not show or prove much yet but from what I've read it is a carcinogen and quite toxic. Anyone else have an opinion or a study that links to it being less scary?
