**Background & Methods** This observational study analyzed monthly cannabis sales data from 450 California retailers during 2020-2021 to examine purchases of flavor-named cannabis products by purchaser age group. ANOVA analyses compared revenue percentages for flavor-named products across six product categories, seven flavor types (sweet, fruit, food, seasoning, food brand, alcohol), and two age groups (young adults 21-24 vs. older adults 25+). **Key Findings** - Flavor-named products dominated certain cannabis categories, comprising 95% of edible revenue, 64% of concentrate revenue, 53% of flower revenue, and 52% of vapor pen revenue, but only 15% of absorbable products (tinctures, sublinguals, capsules, topicals). - Sweet- and fruit-named products accounted for nearly half or more of inhalable category (flower, concentrate, vapor pen, pre-roll) revenue and demonstrated statistically significant upward trends over the study period (p's < 0.05). - Young adults (ages 21-24) purchased higher percentages of sweet- and fruit-named inhalable products compared to older adults (25+) (p's < 0.01), suggesting differential appeal to younger purchasers despite California regulations prohibiting youth-attractive labeling. **Dosage & Administration** Not reported. **Safety & Adverse Effects** Not reported. **Evidence Quality** This observational study provides descriptive market data but has notable limitations. The study examines only California retail data and cannot establish causation regarding flavor preferences or youth attraction. No individual-level data on purchaser characteristics beyond age group was collected, limiting understanding of demographic drivers. The age cutoff (21-24 vs. 25+) represents a narrow window for "young adults" and may not capture initiation patterns in the actual target demographic for youth-protection regulations (minors). The study does not measure actual youth access or consumption outcomes. The authors acknowledge that additional research is needed on regulatory effectiveness. This represents a surveillance-level review rather than a controlled trial, placing it at moderate evidence quality for identifying potential policy concerns but not for evaluating causal mechanisms or intervention efficacy.
