Is it safe to vape 20mg nicotine?
Yes, you can vape 20 mg, but don’t do it on a 100W beast unless you want your lungs to file for divorce. This is the maximum legal limit in Europe, perfect for heavy smokers, but it should only be used on low-power starter kits or pods.
The 20 mg/ml limit is set by the European TPD Directive. At this concentration, nicotine salts are highly recommended for comfort. Using this level in a high-power sub-ohm atomizer would lead to an immediate overdose and unbearable throat irritation.
