AI assistance

MORIE was developed with substantial assistance from frontier AI assistants. The author retains full responsibility for the code, the methods, and the scientific claims. AI assistance accelerated implementation but does not change the attribution of the work.

This disclosure is included for transparency; it does not transfer authorship, copyright, or licensing obligations away from the human author. Where AI-generated code reproduces material from training data verbatim, the upstream licence governs that material; the author has reviewed the source for any such cases.

Anthropic Claude

Anthropic’s Claude family — Opus, Sonnet, and Haiku across the 4.x generation — was used extensively throughout development for code generation, refactoring, documentation, code review, and design discussions. Use was supported by the Anthropic research-credit program.

Google Gemini and Vertex AI

Google’s Gemini 2.5 models — Pro and Flash — running on the Google Cloud Vertex AI platform were used extensively for additional code generation, cross-checking Claude-generated code, multi-modal data analysis, and prototype evaluation. Use was supported by the Google research-credit program.

Data acknowledgments

Several MRM analyses use Statistics Canada and Health Canada Public Use Microdata Files (PUMFs):

• CCS — Canadian Cannabis Survey (Health Canada, annual since 2018; multiple cycles 2018-2024).

• CSADS — Canadian Student Alcohol and Drugs Survey (2021-22, 2023-24; previously Canadian Student Tobacco, Alcohol and Drugs Survey / CSTADS, 2014-2022; previously Youth Smoking Survey / YSS, before 2014).

• CSUS — Canadian Substance Use Survey (2023, 2025).

• CADS — Canadian Alcohol and Drugs Survey.

• CPADS — Canadian Postsecondary Education Alcohol and Drug Use Survey (2019-20, 2021-22).
