Can hepatitis b be drug induced?

Yes: I am not sure, but I think what you are asking is if you can get Hep B by using IV drugs (like heroin)? If so, the answer is unfortunately yes. Sexual contact and shared needles can both result in Hep B transmission, which is spread via blood or bodily fluids. My advice is, always practice safe sex, don't share needles, get vaccinated against Hep B, and get tested.
