CBN became a designated substance on 2026-6-1.The Ministry of Health, Labour and Welfare prohibits in principle the manufacture, import, sale, possession, and use of CBN-containing products. While procedural exceptions exist for medical and research uses, they do not permit general consumer purchase or use. Do not rely on older reviews or past articles claiming "legal" or "recommended."

In addition, category-specific residual limits for Δ9-THC took effect on 2024-12-12, and any product exceeding the threshold is classified as a narcotic. These figures are product concentration standards, not intake guidelines.

Product Category	Residual Limit for Δ9-THC
Oils and fats (liquid at room temperature) and powders	10ppm
Aqueous solutions	0.10ppm
All other products (confectionery, solids, VAPE liquids, etc.)	1ppm

Product appearance or naming alone does not determine whether an item falls under the oils/fats category.
