When you find that you have idiots cooking meth in the attic you will smell odors ranging from cat pee to a strong musty odor coming from the vents or through the sheet rock. If you ever wake up and think you see shiny powder coming from the ceiling, you do. It is not the fairy god mother. That would be white phosphorus from cooking meth and it is highly toxic. Chemicals like that can penetrate sheet rock and everything else. There may be orange stains on your porch and driveway and any concrete around your house. That blows out of the soffet. If every night you hear the same sounds in your attic you might have illegals waiting until you go to sleep to cook. They are extremely sneaky and when doing meth they don't move around much. I have smelled it in Walmart, Arby's, the hospital, doctors office to name a few. It is everywhere and if you smell something that you can't identify it is probably meth cooking. It is sickening. I will be glad when people figure this out so something can be done. All you do is research meth on the net. Cutting roof hatches (trap doors in your roof) is the thing now. All of the meth is not coming from Mexico it is being cooked in attics right here.
