Shomeone doesn't understand their neurology. Or would it be pharmacokinetics? I guess maybe both, because "thrilling" things primarily involve adrenaline and norepinephrine, only involving dopamine indirectly, and as for pharmacokinetics you can inject a person with as much dopamine as you want and it's not going to do anything, as it wouldn't cross over into their brain. You'd basically have to inject dopamine directly into the pleasure centers of their brain to get any kind of emotional reaction, and even that's being debated in the scientific community at this point (it's thought things could be far more complex than just dopamine=pleasure, but I could go on all day about it, so I'll just stop there).

But science is intimately familiar with a way to increase dopamine levels in the brain by a lot. It's called doing amphetamines or cocaine, and thrill seekers and generally intense people do tend to seem to really gravitate towards the stuff. However, while becoming a meth/coke addict is tragic, I don't think I'd call it creepy.
