I use carbon filters on my bong when smoking and notice something really concerning. The bottom filter is brand new. The next up is what one looks like after 5 or 6 fat bong rips, of normal flower, normal blackish resin. The top two are both one hit each of an infused preroll that I purchased from a Maryland dispensary and tore apart and put in the bong. Both filters clogged instantly before I could even pull all the smoke through. And both have this thick tan substance. I’m really glad the filter caught this and not my lungs. Does anyone have any idea why this happened? I’m a liscenced cultivator myself and I’m at a loss of words but this flower doesn’t seem safe to me.
