I always use a water piece these days, got the 14mm adapter when I got the kit. But before that, occasionally yes. If you’re not already, always do a hand break of your flower, a grinder gets it too fine. Fresher herb is always better of course. And a gentle inhale is key. But yeah it’s possible to do all that and still sometimes get bits here and there. Hence my personal switch to water. There are also some aftermarket stems that have twisting pathways, namely for cooling vapor but also has the side effect of catching herb bits as soon as a lil resin builds up.
