Dude you are so wrong.  First off, weed is not nearly as carcinogenic as cigarettes, it has not been proven to cause cancer at all.  It does however, contain more tar.  But your body can easily clean out tar, just take a break.  Also me and my friend smoke cigarettes all the time, and we can and do frequently drop it like nothin at all.  I'm not a real smoker, but I'll go from having 4-5 cigs a day to 2, down to none.  Not that big a deal.  Also, cigars are way dirtier than cigarettes, because they have no filter and you're smoking way more.  They are classier, but you can't really compare them because they're totally different.  I love how people constantly say ignorant shit such as this.
