One hitters brings hot smoke directly into your throat. The larger the chillum, the colder the smoke gets, and the more smoke you'll get in your lungs. The more smoke you'll get, the more of your head you'll get... For a more mellow smoke, pick a smaller one hitter. The Chillums is a pipe used by Indian sadhu, as well as Rastas of Jamaica. For them smoking a chillum is always better than smoking a cigarette: its faster and they don't need any tobacoo.
