Genetics, Pollution, Family history.
Answer:
A) Alcoholism is strongly tied to genetics, and children of alcoholics are more likely to become alcoholics themselves.
Explanation:
<u><em>The alcohol</em></u> is considered by many as a <em>¨legal drug¨</em>, it has extremely harmful health effects and, ironically its consume is normally allowed in every country around the world.
Since it is a drug that generates addiction and dependance, like other ones, it modifies the brain functioning (neurotransmitters and dopamine receptors), provokes genetic mutations (the OPRM1 gen, in charge of the opioid receptions) between others.
Due to these internal changes, <u><em>the 1st-degree family members</em></u> of the alcoholic individual ( children in this case) will be more likely to develop a future alcohol addiction (between 3 and 4 times more compared to a child of a non-alcoholic).
