Addiction and genetics

"Addiction is estimated to be about 40% to 60% heritable, meaning genetics likely account for about half of a person's risk.
That means the other half of addiction risk comes from environmental, social, and cultural factors, like "being exposed to peer pressure, individual coping skills, chronic pain, depression, the properties of drugs themselves," said Zena Samaan, PhD, of McMaster University in Canada, who studies the genetics of addiction."
