Re: How many bowls per day?
A good week scores be 5 bowls (1 a day), bad week is none. I try NOT to smoke more than 1 bowl a day as it messes up my throat something wicked (like the time I hit the new lounge - 5 bowls later and almost 5hr later, I felt like I could barely walk, let alone talk - LOL). For the most part you'll find most people tend to control their intake - either because of time, cost, or other reasons (like health). Some will smoke more, some less.
And I shall echo the others - smoking ANYTHING at all is NOT healthy. So there is NO min amount one can safety smoke. Even if it's Herbal Shiaha - which is sugar cane mulch (think what that might be doing to ya).
