Abstract
We clarify Dr. Narita's concerns by replacing subjective wording with data‐based statements, emphasizing the descriptive—not causal—nature of our analysis, and noting that logistic regression was exploratory. Our findings show both progression and non‐progression pathways, indicating no single dominant gateway pattern among Japanese cannabis users.
