Alcohol and Marijuana Use by Southern California Adolescents Predicts Poor Academic Performance and Health Problems
Adolescents who use both marijuana and alcohol during middle school and high school are more likely to have poor academic performance and mental health during high school, according to a new study by the nonprofit RAND Corporation that followed a group of students over a seven-year period.
However, the study found marijuana use was predictive of poorer functioning across more areas, including lower academic functioning, being less prepared for school, more delinquent behavior and poorer mental health. The results are published online in the journal Addiction.
Findings also show that when youth are using alcohol and marijuana at the same level, nonwhite youth tend to experience poorer functioning than white youth. For example, Asian and multiethnic youth reported more physical health problems than white youth.
Among those using alcohol and marijuana at the same level, Asian, black and Hispanic youth reported being less prepared academically than white youth and Hispanic and multiethnic youth reported lower academic performance than white youth. Click to read more....
