I started at 24 mg and quickly went to 18 as it was too much. I began trying new flavors and when I tend to find one I really like I buy a Lowe nic because I vape that flavor more often. Currently 9 is the highest I have and the rest are 6. I tend to only vape 6. Started a month ago, and before smoked a pad Marlboro lights. I really like peppermint and apple pie, which is weird because I didn't like flavored analogs or menthols at all.
