B – 59 Recreational Drug Use Predicts Self-Reported Attention, Memory, and Academic Problems.

Clinical Context
Background information relevant to the evolving cannabis medicine landscape.
Clinicians should counsel patients that recreational cannabis use is associated with self-reported cognitive deficits in attention and memory, which may have direct consequences for academic and occupational performance. Understanding this relationship helps practitioners identify potential contributors to cognitive complaints in their patient populations and supports risk-benefit discussions when patients consider or continue cannabis use. These findings underscore the importance of screening for cannabis use patterns in patients presenting with attention or memory problems, particularly younger adults where academic impacts may be significant.
This cross-sectional survey of 412 adults aged 18 to 75 examined associations between recreational drug use and self-reported cognitive impairment using validated instruments for substance use history and neuropsychological function. The study found that cannabis use was associated with subjective complaints of attention difficulties, memory problems, and academic performance issues, suggesting cognitive side effects that extend beyond acute intoxication. While self-reported cognitive complaints do not establish causation or objective functional impairment, these findings align with existing literature on cannabis-related cognitive effects and warrant consideration during clinical assessment of patients using cannabis, particularly those in school or cognitively demanding occupations. Clinicians should counsel patients, especially younger users with developing brains, about potential impacts on attention and memory, and monitor for these symptoms during routine cannabis use screening.
“This is an observational survey study, so we need to be careful about causation—we can’t tell if cannabis use caused the cognitive complaints or if people with existing attention issues were more likely to use cannabis—but the association itself is worth taking seriously in clinical conversations with patients, especially younger ones still developing their cognitive skills.”
🧠 While this cross-sectional survey adds to literature documenting associations between cannabis use and self-reported cognitive difficulties, clinicians should interpret these findings with appropriate caution given the study’s reliance on self-report measures, lack of objective neuropsychological testing, and inability to establish temporal or causal relationships. The broad age range (18–75 years) and inclusion of multiple recreational drugs without clear stratification limits specificity about cannabis-related effects independent of other substance use, polypharmacy, or unmeasured confounders such as underlying attention disorders or academic stress. Self-reported cognitive complaints may reflect actual impairment, motivation or mood changes, or reverse causation wherein individuals with pre-existing learning difficulties turn to cannabis, making it difficult to isolate cannabis as a primary driver. For clinical practice, these results suggest that providers should routinely inquire about cannabis use patterns when patients present with concentration, memory, or academic performance concerns
