It found that 63% of heavy lifetime users and 68% of recent users exhibited reduced brain activity during working memory tasks, affecting decision-making, memory, attention, and emotional processing. • The “Cali sober” trend, where individuals abstain from alcohol but use substances like cannabis and psychedelics, is gaining popularity. This shift is partly due to increased awareness of alcohol’s health risks.
