Does using meth, smoking cigarettes, drinking alcohol and taking heavy doses of pain killers have a greater effect on a transplanted heart than one that isn't transplanted? What is the life expectancy of someone with a transplant that is abusing it?

I know someone who abused meth that had to get a heart transplant because of it and the person is abusing it again. This person was also an alcoholic who had been to rehab and relapsed, a heavy smoker and just abused their body. Since the transplant this person has gone back to all of their old habits and I'm concerned with what kind of an effect it will have on the new heart.
