The following link debunks one of the many made up science warnings floating around the Internet.

But, this part caught my eye.
QuoteThe information in the warning message is untrue. The coating on scratch tickets is made of specialized latex inks. There are no credible references to a compound called "Silver Nitro oxide". There are no credible medical or scientific reports that suggest that scratch ticket coating has been linked to skin cancer. There are no credible references to an organization known as the "Medical Research Authority of the US". The warning is a hoax and should not be forwarded.
I never thought about what the scratch part of a scratch ticket is made of. I wonder if anyone has ever reacted to the latex? Or does the UV change it?
Latex doesn't always mean natural rubber latex. It describes a type of compound, synthetic or natural.
Those scratch off things squick me out, though. I make someone else do them (on gift cards and the like).
