These un seen chemtrails are causing parasites, fungus, and worms. Be ware it is being done by the gangs, that are from other countries like China, and Illegal Mexicans. It smells sweet, but then smells like crap, and stayes in your nostils for a day or two.
The bad thing is some people can smell it, and others can not. If you are being targeted by gangs are they are likely being used on you. The State of New York states this is not unusual for people have various amounts of smelling ability. Good luck
