Most people who have permanent liver damage are IV drug users. Not saying it's impossible for those taking pills orally but the liver is very resilient. It would be the exception to the rule that your liver would have problems if it's okay now and you don't have a history of IV drug use. If there is a significant IV drug using history it could still happen. God bless.
