How to Read CBD E-Liquid Concentration (10%, etc.) | Correction of Past Medical Claims and 2026 Regulations

⚡ 【早見表】CBDリキッドの濃度（％・mg）の見方と2026年最新の国内法規制チェック

濃度（％）＝「ボトル容量に対するCBD含有量の割合」	例えば10mlボトルで「濃度10%」ならCBDが1,000mg、「濃度3%」なら300mg含まれています。初めての方はむせにくい低〜中濃度（3%〜5%前後）から試すのが鉄則です。
医薬品ではない（治療・医学的効能の断定は不可）	CBDベイプやリキッドは仕事終わり等のリフレッシュ・嗜好品であり、特定の症状の治療や医学的効果を保証するものではありません。
2026年最新の法規制（THC残留限度値・COA）確認	必ず日本の改正大麻取締法（水溶液1ppm等のTHC残留限度値基準）に完全適合し、第三者機関の成分分析書（COA）が公開されている国内正規ブランドを選んでください。

Corrected on 2026-10-20:We have completely retracted the statements from our 2019 publication claiming 'poor health is caused by cannabinoid deficiency,' 'the proper inhalation method of holding vapor in the lungs,' and 'recommendations for high-concentration 10% e-liquids.' The original publication date is retained.

Do Not Self-Diagnose Poor Health as 'Cannabinoid Deficiency'

Interpreting symptoms such as insomnia, fatigue, or pain as 'a lack of cannabinoids in the body' and attempting to supplement them with commercially available CBD e-liquids or oils is not medically appropriate. If you have symptoms, please consult a medical institution.

Why a Higher CBD 'Concentration (%)' Does Not Mean Safer or More Effective

Labels such as '3%' or '10%' on e-liquids merely indicate the proportion of CBD relative to the total container volume and do not guarantee the amount absorbed by the body or product safety. Because higher-concentration products carry a greater risk that trace impurities from raw materials (such as Δ9-THC or the designated substance CBN) become concentrated and exceed legal limits, checking the lot-specific Certificate of Analysis (COA) is even more important.

CBD, THC, and CBN Are Different Substances: Check the 2026 Regulations

CBD (cannabidiol), CBN (cannabinol), and Δ9-THC are distinct compounds treated differently under Japanese law. Product names or package labels such as "CBD Product" or "Hemp-Derived" alone cannot determine all contained ingredients or legal compliance.

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." Source:Ministry of Health, Labour and Welfare: Designation of CBN and Procedures.

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. You must verify the actual product category against a lot-specific Certificate of Analysis (COA). Source:Ministry of Health, Labour and Welfare: Legal Amendments and Residual Limits.

4 Certificate of Analysis (COA) Checkpoints Before Purchase or Use

Match Between Product Name and Batch / Lot Number:Whether the lot number printed on your actual container matches the lot number on the report rather than a generic sample certificate.
Testing Laboratory and Analysis Date:Whether the name of the third-party laboratory, date of testing, and analytical method are clearly stated.
Limit of Quantification (LOQ) and Limit of Detection (LOD) for Δ9-THC:Whether testing sensitivity is below Japan's category-specific residual limits (10ppm / 0.10ppm / 1ppm), rather than merely stating "ND (Not Detected)."
Absence of Designated Substances (Such as CBN) and Undeclared Ingredients:Whether CBN, a designated substance since 2026-6-1, is confirmed absent.

Avoid using products without verifiable lot numbers or items from unverified sources such as social media or flea-market apps, as actual contents may differ from the label.

Why "Safe Because It Is CBD" or "Side-Effect-Free Because It Is Natural" Cannot Be Assumed

The U.S. FDA highlights risks associated with CBD including liver injury, interactions with concurrent medications, pronounced drowsiness, diarrhea, and appetite changes, while noting scientific unknowns regarding long-term use and differences across intake routes (inhalation, oral, topical). Source:FDA: Risks and Unknowns of CBD Products.

Research on specific prescription CBD formulations cannot be treated as proof that commercial CBD oils, gummies, or VAPE liquids improve insomnia, relieve stress, boost immunity, or aid smoking cessation. Discontinue use immediately and consult a medical professional if you feel unwell. Anyone with preexisting conditions or taking medication should consult a physician or pharmacist rather than self-medicating.
