adrenaline junkie

Craves dangerous excitement

A person who craves the rush of excitement from dangerous or thrilling activities—skydiving, BASE jumping, extreme sports.

The metaphor casts the body's stress hormone as an addictive substance and the thrill-seeker as someone hooked on it: He's such an adrenaline junkie—last week it was bungee jumping, this week cliff diving.
