Abstract (en)
[origin: US2004003822A1] The present invention relates to a biodegradable dual density cigarette. The invention provides for a cost-effective process that ensures that the non-filter cigarette has smoke delivery quality comparable to that of a conventional filter cigarette. The invention also substantially reduces the tar and nicotine contents. The dual density cigarette is biodegradable and therefore environment friendly.
