Overview

• Trained teams began in-home visits in late July, randomly selecting residents aged 12 to 65 for standardized questionnaires on drug and alcohol use, emotional health, gambling and videogame habits.
• Surveyors wear navy blue shirts bearing Secretaría de Salud and INSP logos and carry cream-colored official IDs with holograms on institutional lanyards to verify their credentials.
• Data collection runs through October and will cover nearly 24,000 households with 17,591 interviews to ensure regional representativeness and comparability with past national surveys.
• All responses are anonymized and strictly confidential, with authorities pledging to use findings exclusively for statistical analysis and to shape public prevention and addiction-care strategies.
• The 2025 relaunch restores the national survey after its 2022 cancellation and the last data from 2016, closing a critical gap for tracking substance use and mental health trends.
