Maybe this will help I did a little research There are approximately 20 drops of Smoke Juice per milliliter. Example using 24mg Smoke Juice, there would be 1.2mg of nicotine per drop (24mg ÷ 20 drops). A Regular cigarette contains approximately 1.2mg of nicotine in each cigarette, or 24mg of nicotine per pack (1.2mg x 20 cigarettes). A Light cigarette contains approximately .7mg of nicotine in each cigarette, or 14mg of nicotine per pack (.7mg x 20 cigarettes). A Ultra Light cigarette contains approximately .5mg of nicotine in each cigarette, or 10mg of nicotine per pack (.5mg x 20 cigarettes).
