Can you get ink poisoning from tattoos?

Maybe.

You may have a problem in the form of an allergic reaction, however tattoo ink composition is rarely published for you to read, so one can never be sure of what you are really getting, the best you can do to avoid problems it to get a 'patch test'.

A patch test is a method wherein your artist tests a particular ink on a small section of skin to note if you have an adverse reaction before beginning the real tattoo. Black ink is usually relatively inert, while colors, such as red inks can be more prone to cause allergic reactions.
