Researches have been looking for decades for different reasons why people have addictions. They have recently discovered that addictions to alcohol and some drugs can be linked to a specific gene. They have not currently found much information on it. They just know it could have to do with genetics.

Once researchers can find exact genetic variants and molecular mechanisms, then we can create much more effective, even personalized, treatments for individuals addicted to a variety of substances. They are still conducting a lot of research in this area. Hopefully they will find a lot of helpful things!
