sniffaholic 

A person who is enslaved by their own highly developed sense of smell, often to their own detriment.

He was entirely compulsive about it, a complete and total sniffaholic, a person unable to not smell every single item and surface he came across!

surfaholic

Addicted to web surfing. As I am.

Also works for wave surfing!

My name is Bob, and I am a surfaholic.

I just surfed for seven hours nonstop. I believe this qualifies me as a chronic surfaholic.
