RE:Cigi's June 19 to now....lol...blah, blah, blah...= NOTHINGI'm sorry. This cigi thing seems like a terrible idea but I've been wrong before. Also, JM states that filters are used to make it less harmful to smoke. I've actually read articles stating the filters make it worse because it filters out all but the finest particles which means they penetrate the lungs deeper. That may also help the user get 'higher' if used in a joint. Either way, they have have prerollers. But sure why this thing is required, mass scale???
