How much of vitamin c one ciggarette use?

25-100 mg: I've read that each cigarette depletes our bodies of 25 mg of vit c but am not sure where that number comes from. Many experts advise smokers consume at least 2000 mg of c/day, which is 100 mg per cig if you smoke a pack a day. This won't totally protect you from the immense damage caused by smoking but will reduce that damage somewhat. See http://www.Mcvitamins.Com/health%20opponents/smoking.Htm.
