If it is true, it can be a real health hazard to move into that type of home. MSN Real Estate recently wrote an article addressing this problem.
In part the article said, "Making or even smoking meth leaves behind a stew of chemicals that saturates walls, ceilings, floors and carpets with meth as well as mercury, lead, iodine, lithium and poisonous solvents. For each pound of drug, meth "cookers" dump, flush or leave behind 5 to 6 pounds of poisonous waste.
Exposure to even small amounts of these poisons can damage humansâ€™ nervous systems, liver and blood production mechanisms. Small children suffer most. Exposure can trigger birth defects and developmental problems in babies in the womb."
