| 1 | Is a THC vape product permitted in the target market? | There is no single EU-wide consumer THC-vape limit that makes a product lawful. THC controls and permitted cannabis uses are determined largely by national law. In the UK, THC is controlled, while cannabis-based products for medicinal use are subject to a separate regulated pathway. | Confirm the product’s legal classification, permitted route to market, and any national licensing or prescription requirements before relying on an ingredient threshold or a laboratory result. | EU member-state controlled-drug rules; UK Misuse of Drugs Act 1971 and Misuse of Drugs Regulations 2001. |
| 2 | Does a hemp threshold apply, and what does it actually measure? | In the United States, the federal statutory definition of hemp uses a limit of no more than 0.3% delta-9 THC on a dry-weight basis. That definition is not a nationwide authorization for intoxicating vape products; state and other federal requirements may be stricter or different. | Document the analyte, calculation basis, sampling method, and applicable jurisdiction. Do not treat a hemp classification or one passing test as proof that a finished vape product can be sold everywhere. | U.S. Agricultural Improvement Act of 2018, section 10113, amending the definition of hemp in the Agricultural Marketing Act. |
| 3 | Is there a maximum THC amount per package? | Canada’s federal adult-use framework sets a maximum of 1,000 mg THC per immediate container for a cannabis extract, a category that includes cannabis vape products. Provincial and territorial rules also affect sale and distribution. | Check the total THC in the immediate container, not only the concentration per millilitre or per puff. Confirm that packaging, labels, product classification, and provincial or territorial requirements also comply. | Canada Cannabis Regulations, including requirements for cannabis extracts and packaging. |
| 4 | Does the market use a residual-THC threshold rather than a permitted product limit? | Japan applies residual-THC concentration standards that include 10 ppm for oils and fats, 10 ppm for aqueous solutions, and 1 ppm for other categories. These are control thresholds; they should not be interpreted as permission to market an intentionally THC-containing vape product. | Determine how Japanese authorities classify the specific formulation and matrix before testing. Use a suitable validated method with a reporting limit below the applicable threshold, and confirm current requirements with the competent authority. | Japan Ministry of Health, Labour and Welfare rules on residual THC concentration standards for cannabis products. |
| 5 | Which laboratory tests are required for each batch? | Canada’s federal cannabis rules require applicable cannabis lots or batches to be tested for cannabinoid content and specified microbial and chemical contaminants before sale. The exact requirements depend on product class and the applicable regulations. | Build a product-specific test plan covering the required cannabinoid measurements and contaminant panels. Use appropriately authorized laboratories where required, retain batch records, and confirm that the certificate of analysis matches the finished product and lot. | Canada Cannabis Regulations, Part 5 (Testing). |
| 6 | Do e-cigarette rules for nicotine also authorize THC liquids or devices? | No. The EU Tobacco Products Directive sets rules for nicotine-containing e-cigarettes, including a nicotine concentration limit of 20 mg/ml; it does not create a THC-vape authorization or a THC limit for consumer products. | Assess the liquid, device, labeling, and intended use under the separate rules that apply to each. A device’s compliance with nicotine-vape requirements does not establish that its THC contents are lawful or compliant. | EU Tobacco Products Directive 2014/40/EU, Article 20. |
| 7 | Do rules vary by state, territory, or product category? | Yes. In Australia, medicinal cannabis follows a therapeutic-goods and prescription framework, with additional state and territory controls; there is no general consumer THC-vape limit that applies uniformly across the country. In Switzerland, the 1% THC distinction used under narcotics law does not remove other product-category requirements or automatically authorize a vape for sale. | Map each destination and sales channel separately. Confirm product authorization, manufacturing and quality standards, import controls, advertising restrictions, and local possession or dispensing rules before distribution. | Australia: Therapeutic Goods (Standard for Medicinal Cannabis) (TGO 93) Order 2017 and applicable state or territory rules. Switzerland: Federal Narcotics Act and applicable product-specific legislation. |
