A Budtender’s Guide to Cannabis with Tessa Dattillo

Tessa Dattillo, a cannabis bud tender and educator known as Tessa420 on TikTok, reveals the hidden realities of dispensary work in Illinois—where overstimulation, misinformation, and regulatory confusion often prevent meaningful patient education. Despite being barred from discussing terpenes or minor cannabinoids like CBG and THCV, Tessa uses symptom-based language to guide medical patients toward effective products, advocating for a shift from diagnosis-driven claims to experience-focused recommendations. She shares shocking stories of customers mistaking THCA for illegal spice and being hospitalized after consuming 42% THC flower, underscoring how drastically cannabis has changed since the 1970s. Tessa also exposes the industry’s blind spots: the lack of public consumption spaces, the dominance of edibles over flower, and the prevalence of misleading products like 'cannabis sand' and oversized vapes. Her advocacy for bud tender education, patient empowerment, and the creation of product flight samples highlights a growing need for systemic reform in cannabis retail. Tessa’s personal journey—from working in California’s early legalization era to becoming a trusted guide in Chicago’s complex market—reveals a deep commitment to harm reduction and patient dignity. She champions the use of whole-plant products, shares innovative consumption hacks like mixing RSO with Tylenol, and emphasizes the importance of cross-checking cannabis with prescription medications.
