Medscape (3/23, Brooks, Subscription Publication) reports, “Substance use disorders (SUDs), including alcohol, tobacco, cannabis, or opioids, appear to share a common genetic signature,” researchers concluded in a “genome-wide association study” that “looked for variations in the genome that were closely associated with SUDs in more than one million people of European ancestry and 92,630 people of African ancestry.” The findings were published online March 22 in the journal Nature Mental Health.
