Is it a must to change the needle after sucking out juice?

I found a picture for you ealier showing the burr that is created after an injection, but I lost it. I have a picture (not a close up) of what happens to the needle after a couple of injections.

I also found a website while I was surfing that everyone might find interesting. Needle-free Injections. The link is to the intramuscular one, but you can find all kinds of info about it at the homesite... www.bioject.com .
