Your not gonna hurt it by smoking multiple times, a good rule of thumb is one day off for each bowl, but even if you don’t rest it the worst that will happen is that it might go sour and you have to deep clean it.Not going to lie - on third bowl of plum pudding today... same Milano all day too... shame shame. I couldn’t help myself - need more pipes still, but this one is fine for multiple bowls in a day... it has a few days off ahead.
