L'alcool ha effetti più dannosi della marijuana sul tessuto cerebrale degli adolescenti. E' la conclusione a cui è giunto uno studio condotto dall'Università di San Diego, che sarà pubblicato sulla rivista "Alcoholism: clinical&Experimental Research".
Secondo la ricerca, i giovani che consumano almeno cinque o sei drink due volte alla settimana vedono ridursi "la materia grigia", con conseguenze sulla memoria, l'attenzione e la capacità di prendere decisioni. I ricercatori hanno condotto lo studio su 92 adolescenti, di età compresa fra i 16 e i 20 anni.
