I would love to make this happen on some sort of mass scale. Everyone would have to pretend they weren't creating colored clouds when asked, like, "Naw man, I have no idea what you are talking about! Same white cloud as always.... What are YOU smoking." Even if 20 smokers were insisting you were "blowing purple," you'd have to refuse to admit it. Ever.
I coulda used that fun in Walmart today.
