Forum:Is Jack immune to Adam?

Alright so I couldn't find any information on this, but Jack seems to be practically immune to any detrimental effects of Adam. By the age of one year he weighed 56 pounds and had the gross musculature of a 19 year old, so most of his body was made from Adam. Then he spent around 4 years before returning to Rapture without any Adam, and his body was stable enough for him to remain healthy and sane in that period. Also during the events of Bioshock he splices himself up very much, and in the good ending (which seems to be the canon one) he has lived into old age and the little sisters have grown up and married, yet he appears to be fairly healthy and sane (for someone of his age, if we consider him to be around 18 years older than is chronologically true because of his accelerated growth during his first year of life). If this is true then his body would be nearly priceless to a scientist that works with Adam, to find a possible way to use it in a stable and healthy manner. I will admit that Jack does, however, inherit other people's memories through Adam and sees the ghosts just like everybody else.
