I would stay as far away as possible. Cameras can be replaced easily, lungs can not.
One of my friends is big into spinning wool and uses Kool-Aid to dye the wool. That's right.... Kool-Aid.... the powder that people mix to make drinks for their children.... the same stuff that's approved for human consumption... It makes vibrant colors that will not wash out... just imagine what it does to your insides
Just because doing something is not banned (dousing crowds with fine powder) does not make it a good idea.
Sweater made of wool dyed with kool-aid powder. Apparently, kool-aid works better than most commercial dyes... and remember red dye #2 in food products... added to food for decades and approved by various health departments... and then they found it caused cancer...
I would not breathe in that stuff.
