Subject: Is there such a thing as arsenic addiction?

I was reading on the internet about a possible Jack The Ripper suspect called 
James Maybrick.  On this website, 

http://www.casebook.org/suspects/james_maybrick/maybrick.html

... it stated he was addicted to arsenic.  It also says people were frequently 
addicted to arsenic and stryrchnine in Victorian times.  It sounds fascinating 
and I'd like to hear more about this odd subject.  Is it that people took it 
for "lustrous eyes, whiter skin, increased virility" then couldn't stop?  
Wouldn't this kill you before you became addicted?  Is anyone addicted to 
arsenic in modern times?  Wow...
