Swedish regulation now requires producers and consumers to obtain a permit for the sale and use of e-liquid that contains more than 17 mg of nicotine per ml. This is because European regulations now classify these e-liquids in toxicity category 3, which need a permit under Swedish law.
According to our interpretation, these obligations constitute a de facto ban on high-nicotine concentration e-liquids, as the process of obtaining these permits is so stringent.
