Sir you are a retard. You are basically saying that a cigarette that contains over 4,000 chemicals is worse than a plant that has no chemicals put into it. Yes they both contain tar. But you look at a person that goes through 30 cigarettes in a day (pack and a 1/2) then look at your 1 a day stoner that sparks up 1 bowl. Depending on how big your bowl is the weed only equates to about 1 cigarette. Meaning that those who use cigarettes are at much higher health risks than those who smoke some devils lettuce. This is called critical thinking. Some day you too could develope this skill. (There are also studies to support my thinking)
