A study suggests that continued marijuana use into adulthood,
particularly beyond age 30, can have negative effects on brain function and mental health. Research indicates that long-term use is linked to cognitive decline, memory impairment, and an increased risk of mental disorders like anxiety and depression. The brain’s ability to process information and learn may also be hindered by persistent cannabis consumption. While occasional use in adulthood might not have severe consequences, habitual smoking may lead to long-term health issues. Experts emphasize moderation and awareness of potential risks for users, especially those in their 30s or older.
