If HIV is unable to reproduce outside its living host then how it is transmitted by sharing a needle

It is not the sharing of needles that is the risk. Drug users use the same needs and syringes to share drugs. When on user injects street drugs into his/her blood stream blood is also drawn up onto the air tight syringe (please note it is air tight). This syringe is then pasted onto another user who injects infected blood from the air tight syringe along with the street drugs into their own blood stream. Even though HIV is kept infectious within this enclosed environment to pose a risk of an infection the clocks is ticking all the time. It is the mixture of drugs within this enclosed environment and the time scale it takes that poses a risk, not because HIV remains infectious outside of the human host and exposed to air.
