Are you sure you don't mean Liver drugs? As in drugs that can damage your liver?
Inside the body you can - "spilt livers" (pieces of liver from adults) are regularly used for child's liver transplants, if a suitable size donor is not available. The piece of liver grows as the child grows, reaching a normal size. (But I don't know if the lobes appear in the same way that you would expect on a standard liver).
The worst drug available- alcohol. There are others, but alcohol is the most common.
There is no function of the liver to drugs, but rather drugs affect the liver. My grandma has been on drugs for so long that now her liver is failing.
The first human liver transplant was performed in 1963, and since then, thousands of liver transplants are done every year.
Alcohol damages the liver ~ Therefore a transplant is needed if this hapens.
