maybe im just weird or somethin but i dont know wut u guys r talkin about, i love smoke rings w/ weed its always thicker and better my rings r just better, but i still take the smoke into my lungs, i dunno but anyways ya there r a couple ways to do it but i prefer the way chillstoner described, he made it sound a little complicated but the way i do it is just make a nice O about the size of the head of a water bottle (the part u drink out of) and then make sure ur tongue is in the middle of ur mouth not touching any sides and then give a tiny cough, this part is the hardest esp describing it online but its kinda just like flexing ur throat, the sound u should be making is is when u say "uh" just downsized alot, this method is pretty easy i picked up real quick the hardest part is just making sure u dont let too much smoke out, these make small rings but u can do them rapid fire and its cool, but awhile back i posted somethin on smoke tricks to see if anyone knew and cool ones and some one described a way to make big rings, it works really well its pretty old and just titled "smoke tricks" i think its under either here in recreational or experiences, good luck man and practice practice practice!!
