Another question, I was weak in chemistry in college so need to ask. The bottle of 50/50 with 4mg nicotine I got says 4mg nicotine on the front, but on the label of ingredients it states Polypropylene glycerol etc and 4% Nicotine, is this correct? Does 4% Nicotine equate to 4mg?
My very first bottle of 60 mg nic was "6.0% W/V", Don't know what strength liquid I have , so unless your 4 has a decimal in front of it, it looks to me like you have 40 mg nic.
