A new study reveals that up to 10% of pre-teen children are curious about using substances, with boys more likely than girls to be interested. Parents' rules and home access play a significant role in shaping their children's curiosity, with Black parents being more likely to set rules against substance use.
A new study led by UCL and King's College London researchers found that adolescents are three times more likely to develop a cannabis addiction than adults. However, they do not appear to be at increased risk of subclinical depression or anxiety. In contrast, adult users who become addicted may experience worsening mental health symptoms.
