> This guidance from the Medicines and Healthcare products Regulatory Agency (MHRA) outlines the requirements for all manufacturers and importers wishing to sell e-cigarette and vape products in Northern Ireland. The document does not pertain to a specific company or inspection date but establishes ongoing compliance standards under the Tobacco and Related Products Regulations 2016 (TRPR). The main regulatory issue addressed is the necessity of providing clear data on nicotine uptake. Previous submissions have occasionally lacked the required scientific rigor regarding how much nicotine is absorbed by the user, which is a fundamental requirement for market entry. Under the TRPR framework, companies must submit comprehensive reports detailing the efficiency and speed of nicotine delivery. The required actions involve performing standardized laboratory testing or clinical evaluations of their products and submitting these findings via the MHRA’s notification system. Any product notification that lacks this nicotine delivery data is considered non-compliant and invalid, effectively barring the company from legally marketing the device or liquid. By following these steps, companies ensure they meet the transparency and safety standards necessary for consumer protection in the Northern Irish market.
