My reason for asking is because I learnt of something called auto-tritration as users will smoke for the desired effect. Filters are designed to remove the tar but in doing also filter out the nicotine. So I suppose the question is, do filtered ciggerettes remove more tar than nicotine and by what percentage? If the ratio is excatly the same then filters would have no benefit to users who wished to decrease tar intake according to auto-tritration.
