5mg is as light as nic salts get, and that's exactly the point. The throat hit fades right down, so what's left is flavour, properly tasted rather than chased by a hit of nicotine.
It suits light smokers just starting out, established vapers stepping down from 10mg, or anyone who vapes often through the day and wants to keep total nicotine in check. Works well in refillable pod kits, even ones running a bit higher powered.
