No, these tattoos are created for the show.

I'm not an expert in the field.

But that makes no sense under any circumstance.

Of course, with the exception of entertainment purposes.

I think the only anti-possession tattoo possible would maybe be a cross.

IF you believe in the power of the Christ.

Aside from that (or including, depending on your beliefs) would seem silly.

Your odds of being in a situation where this would even come into play are slim to none. More likely none.

I'm a firm believer in the power of mind.

You could give meaning to any object you choose and use it to protect yourself.

As long as you know it is protecting you from evil, it will.

The mind is very powerful.

I suggest you use it.

You're proper he didn't have it in that episode. That is just a suggestion i would be fully improper, buy possibly when Sammy said sure to Lucifer it went away on account that the tattoo is called an Anti Possession symbol, and considering the fact that it used to be Sam's option to let Lucifer take manage of his body...It come what may went away... Sorry that is my bet.
