Joint filter tips are the little mouthpiece that sits at the end of your rolled joint — holding the shape, stopping loose herb from reaching your lips, and giving you something firm to draw through. This category covers three takes on that job: a pocket tool that rescues half-smoked cones, flavoured squeeze-and-click tips, and reusable glass mouthpieces. Shop filter tips at Azarius, the Amsterdam smartshop running online since 1999.
Buy Joint Filter Tips — Format Guide
Filter tips do three things: they stop scooby snacks (bits of burning herb hitting your tongue), they keep the cone's shape stable as it burns down, and they give the draw some resistance so the joint doesn't run. What they don't do is filter out tar or THC in any meaningful way — a 2000 study in Harm Reduction Journal found unfiltered joints actually delivered a higher cannabinoid-to-tar ratio than filtered ones. So choose a tip for comfort and cleanliness, not for health claims. That's the honest starting point.
Most rolled joints in Europe still use a rolled cardboard roach — free, disposable, works fine. The three products in this category are what you reach for when "fine" isn't quite cutting it anymore: you want flavour, you want a cooler draw, or you've got a half-smoked cone sitting in the ashtray that tastes like a bonfire.
How to Choose a Filter Tip Format
The decision comes down to what's annoying you about your current roll. If it's the stale relight — that acrid hit when you spark a cone you put down an hour ago — you want a maintenance tool, not a new tip. If it's the flat cardboard taste, a flavoured or glass tip is the fix. If you're tired of buying disposable anything, glass is the long game.
| Format | What it is | Good for |
|---|---|---|
| Joint maintenance tool | Pocket cutter that trims charred tips and repacks the cone | Cone smokers who relight often and hate the stale taste |
| Flavoured squeeze tips | Hemp filter with a capsule you click to release flavour | Social smokers, flavour-chasers, anyone bored of plain roaches |
| Reusable glass tips | Borosilicate glass mouthpiece, washable, lasts indefinitely | Daily rollers who want a cleaner draw and less waste |
The RAW Cone Cutter is the one to grab if you're a cone smoker — it solves the relight problem most filter tips can't. Quick Tips are our pick for taste, with six flavours from fruit to mint in the range. Hemper Glass Filter Tips come in two diameters and replace the roach entirely — buy once, wash forever.
Disposable vs reusable — what changes
A regular smoker rolls 5–7 joints a week. Over a year that's around 300 cardboard roaches in the bin. Switching to a glass tip cuts that to zero waste and adds a noticeably cooler draw because glass doesn't combust or leach paper taste into the smoke. The trade-off: you have to clean it, and if you drop it on tile it's gone. Flavoured tips sit in the middle — still disposable, but the squeeze-capsule gimmick actually delivers on taste in a way flavoured papers never did.
Our shop-floor opinion, for what it's worth: if you roll every day, order a pack of glass tips and a cone cutter. That combo handles 90% of the annoyances. If you roll occasionally and like variety, grab flavoured tips for the novelty. Don't overthink it.
Frequently Asked Questions
Do joint filter tips actually filter anything?
Not in the medical sense. They stop loose herb and ash from reaching your mouth and keep the cone structurally sound, but they don't remove tar or reduce cannabinoid loss. A 2000 Harm Reduction Journal study found filtered joints delivered less THC per puff than unfiltered ones. Choose tips for comfort and cleanliness.
Glass filter tips vs cardboard roaches — is it worth switching?
If you roll daily, yes. Glass gives a cooler, cleaner draw with no paper taste, and you'll save roughly 300 cardboard roaches a year from the bin. You do need to wash them, and they break if dropped on hard floors. For occasional rollers, cardboard is fine.
What diameter glass tip should I buy?
7 mm suits standard king-size papers and a normal-sized joint. 10 mm works better if you roll fatter cones or want a wider airflow. Most rollers start with 7 mm — it matches what cardboard roaches feel like in the mouth.
Can I reuse a flavoured filter tip?
No — flavoured tips like Quick Tips are single-use. The capsule releases once and the hemp filter absorbs resin as you smoke. For a reusable option, go with glass.
How do I clean a glass filter tip?
Soak in isopropyl alcohol for 10–15 minutes, rinse with warm water, let it dry. Same routine you'd use for any glass smoking piece. Do it every few joints and it stays clear; leave it a month and you'll be scrubbing.
