No, it is not safe. The helium will enter your blood stream, and cause long term damage.

... Not really... for the most part inhaling a little bit from a balloon to change your voice is not going to do a lot of damage. The problems come when people inhale large amounts over a short period of time or directly inhale it from a pressurized tank. Remember the helium is replacing the oxygen you would normally inhale, thus depriving your brain and other vital organs of oxygen. This can lead to brain damage stroke or death. Also inhaling from a pressurized tank can harm your lungs or even cause bubbles of helium to form in your blood stream which can also lead to stroke or death. http://news.yahoo.com/dangers-inhaling-helium-exemplified-oregon-tragedy-210000333.html

Excessive inhalation of helium can be dangerous. If you just do it once or twice you fine though

It damages brain cells. But a couple whiffs won't hurt you. Have fun :)
