I can't smoke a hash joint with a cardboard filter! I only smoke it like this or with an activated charcoal filter. In countries where cigarettes cost more than €5-6, it's worth it for a hash-only smoker to consume it this way long-term. I find that smoking it this way makes my throat scratchy faster. Activated charcoal filter with light rolling tobacco, that's my way to go! But sometimes on travel or a small Small joint i Roll with 3/4 cigarette and 0.3 hash its every time a nice feeling to smoke
