It's perfectly safe as long as you rinse first. (Obviously don't use this when the drain is *totally* clogged).

 Otherwise every time you clean a toilet you'd be gassing yourself, remember? (stale urine = ammonia, ammonia + bleach = chlorine gas). 

And anytime you use bleach you should make sure to have adequate ventilation (a window open, etc)

Just don't put your mouth on the drain and breathe in, lol ;)
