Question

What is the link between heredity and drug addiction?

Answer 1

Heridity is based on how you were raised that gives you a more likely chance to get addicted because of the people that raised you. 

drug addiction is not genetic it is all your doings unless you were raised difrently.

Answer 2

Answer:

Some people have genes that make it easier for them to become addicted to drugs.

Explanation:

Large studies have shown that the risk of drug abuse is hereditary in up to 60% of cases. This was related to variations in the genome, but these particularities do not fully explain the phenomenon. Evidence has accumulated in recent times that some changes that occur in the chemical markings that lifestyle attaches to the genome, known as the epigenome, can also be passed on to later generations. This would also happen with vulnerability to drug addiction.

From this we can state that the relationship between heredity and drug addiction refers to some people who have genes that facilitate drug addiction.
