Whenever you bring home an animal, if it has teeth, you risk being bitten, no matter how minor or severe. Chances are they are freaking out and with time and trust, they will mellow out. Or not, because we will eventually get that one that wants to be psychotic, no matter the species. Either way, like I said, if it has teeth...
Seriously though, most snakes bite out of fear and they usually do not even break skin. The fear of being bitten is usually amplified in your mind over the actual physical injury of the bite.
