Corrected on 2026-10-20:We have retracted the purchase recommendations for CBN-infused products published in 2024 as well as the blanket assertion that the entire brand is "safe." Product names and ingredient descriptions from the time of publication do not indicate the composition or legality of products sold today. The original publication date is preserved.
When checking the safety of skew, it is necessary not to draw conclusions from the brand name alone, but to separately verify the ingredients of the specific product and lot on hand, certificates of analysis, and current regulations. This article does not recommend purchasing or using specific products, and instead outlines the key points to check.

Regarding Past Guidance on CBN Herb and CBN-Infused Pens
The previous edition contained descriptions recommending "CBN herb" and disposable pens described as containing CBN.We have removed the content recommending their purchase and use.Content published in 2024 cannot be read as guidance that remains usable from 2026-6 onward.
This is a correction of our older article and does not certify that current skew products contain the same ingredients or that the brand as a whole is illegal. Please distinguish between current and past products even if their names look similar.
CBD, THC, and CBN Are Different Substances: Check the 2026 Regulations
CBD stands for cannabidiol and CBN stands for cannabinol. Even though the names look similar, they cannot be treated as falling under the same regulations. One cannot judge all contained ingredients or legality solely from a product name like "CBD product."
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 products containing CBN. While exceptions exist under prescribed procedures for medical and related uses, this system does not permit free use by the general public. Please do not use "legal" or "recommended" claims from older articles or reviews for current decisions. Source:Ministry of Health, Labour and Welfare: Designation of CBN and Procedures.
Regarding Δ9-THC, residual limits for each product category were established on 2024-12-12, and products exceeding those values are classified as narcotics. This is a standard for ingredient concentration in products, not a guideline for intake amounts.
| Product Category | Residual Limit for Δ9-THC |
|---|---|
| Oils and fats (liquid at room temperature) and powders | 10ppm |
| Aqueous solutions | 0.10ppm |
| Other products not listed above | 1ppm |
A product cannot be judged to fall under the oils and fats category solely because it is called an e-liquid. It is necessary to check the actual product category and analytical results. Compliance with THC standards alone does not prove the absence of other regulated substances such as CBN. Source:Ministry of Health, Labour and Welfare: Legal Amendments and Residual Limits.
skew's Current Information and What Cannot Be Verified from It Alone
Checked on 2026-10-20:the official skew websitepresents the brand as a CBD vape brand and lists starter kits, cartridges, and other items. However, the display on this website alone does not confirm the legality or safety of older products you may have on hand or of every production lot.
Import-related images and past "THC-free" explanations introduced in the previous edition also cannot be treated as documentation guaranteeing all current products. Our site has not conducted ingredient analysis or inhalation testing on individual current products.
Key Points When Reading Ingredient Labels and Certificates of Analysis
- Does the lot covered by the analysis match the specific product you have on hand, not just the product name?
- Are the test date, testing laboratory, measured components, and limits of detection and quantification clearly stated?
- Can the Δ9-THC result be compared against the standard for the actual product category?
- Are regulated substances such as CBN or unlisted ingredients left unclarified?
"Not detected" must be read together with the testing conditions and detection limits. Having documentation is separate from having zero health risk across all ways of use. Check with the manufacturer or seller regarding any unclear points.
Being CBD or Food-Grade Flavoring Does Not Mean It Is Safe to Inhale
The US FDA explains risks associated with CBD, including liver injury, interactions with medications you are taking, drowsiness, and diarrhea. It also notes that unknowns remain regarding long-term use and differences across methods of intake. This is official safety information from the US and does not indicate that individual products in Japan have been approved. Source:
Research on specific medical CBD formulations cannot be directly substituted as evidence that commercial vape products improve insomnia or anxiety or aid smoking cessation. Labels such as "high concentration," "naturally derived," or "food grade" alone do not prove the safety of heating and inhaling a product. Source:FDA: Risks and Unknowns of CBD Products.
If you experience any change in your physical condition, stop use and consult a medical institution. If you are taking medication or have an underlying condition, do not use CBD on your own judgment in place of treatment; check with a physician or pharmacist.
