i dont see how water can put in more tar unless water has tar in it. and since i drink gallons of it a week and bath in it every day i think ill take my chances. i suppose it is possible though if there was a chemical reaction with the smoke and water, but still not sure. i have seen things arguing for both as to the thc thing i have never felt a noticeable difference higher or lower except it is easier to take bigger hits out of water. i should like to try this rice method though.
