Yes, there is. One difficulty for those who treat addiction is 'transferred addiction'. The subject may be addicted to alcohol, become sober and not drink again, but will suddenly manifest a hitherto absent addiction to something else. This may be another substance but it may be shopping, buying at auctions (addicts get a 'high' from auctions, because they like instant gratificatiion and the 'thrill of the chase'), gambling etc.
There is good evidence that a tendency to alcoholism is inherited. It was once thought that the child was simply more at risk if he had alcoholic parents, by exposure to alcohol and its parental acceptance. But it's simpler than that. Some people are born with an aversion to alcohol; they may be physically sick on consuming any; some can take it or leave it, and a few get such a rewarding feeling from it that they seek more. The last are at risk from their brain chemistry, which is genetically determined. We often find that the, now alcoholic, child of sober parents has a grandparent or other direct ancestor who was an alcoholic; the addiction 'runs in the family' occurs frequently in the family tree, and afflicts individuals randomly. The upbringing is not the cause, inheritance is.
