FORENSIC TOXICOLOGY

An increase in dispensed packs is a change in supply volume, not a direct count of people starting treatment.

What the supplied source reports

The study examined anxiolytic pharmacy dispensing in Castile and Leon during 2015–2020. Total use measured in packs rose 14.41%, with lorazepam and alprazolam prominent and diazepam showing a larger proportional increase. Dispensing peaked in March 2020 around the onset of confinement.

Limits of the evidence

Pack measures can change with package size, refill timing or stockpiling. The temporal pandemic association cannot independently establish increased anxiety, new dependence or a causal lockdown effect. Aggregate volume does not reveal each person’s duration, dose or adherence.

Implications for forensic interpretation

For interpreting a trend, specify its unit and denominator before comparing it with prevalence or daily-dose statistics. March dispensing may reflect altered access patterns as well as treatment needs. The paper documents a historical regional pattern, not a measure of individual intoxication or a basis for inferring that every additional pack represented a new patient.
