Grinder
A 'grinder' is a piece of equipment used to grind up dried cannabis flower into small pieces (granulate) so it can be more easily and efficiently vaporised.
A grinder is a small tool used to break dried medical cannabis flower into an even, crumb-like consistency (or granulate), making it easier to prepare for vaporisation. A consistent grind can help your prescribed flower heat more evenly in a dry herb vaporiser, which can improve airflow and reduce wasted material.
Most grinders have interlocking teeth that shred the flower when the top is twisted. They are usually made from plastic, aluminium, stainless steel, or the ‘gold-standard’ ceramic-coated metal.
Are grinders necessary?
No, grinders are not 100% essential, but most medical cannabis patients who have been prescribed one or more medical cannabis strains find they make preparation faster, cleaner, and more consistent.
They can also be especially helpful if you have pain, stiffness, tremor, or reduced hand strength, as they make preparing your medical cannabis much easier than other options.
Why are ceramic grinders considered the best option?
Ceramic grinders are widely considered the premium choice because the ceramic surface changes how the grinder behaves over time, especially compared to standard metal or plastic options.
Ceramic grinders are often preferred because they:
- Grind more smoothly and consistently, which supports more even vaporisation
- Reduce sticking and clogging (the flower is less likely to build up inside the chamber)
- Are easier to clean, as residue tends not to cling as stubbornly to the coating
- Maintain performance for longer, since the ceramic coating helps reduce friction and wear
- Feel more comfortable to use day-to-day, particularly if you are grinding regularly
- Because ceramic coatings are more resistant to friction-related wear, they may be a better long-term choice than plastic or basic metal grinders, which can break down faster and potentially leave microscopic debris in the ground flower.
- Resist friction-related breakdown more effectively than plastic or standard metal grinders, which can deteriorate with repeated twisting and may contribute fine particles to the ground flower.
Does the Releaf Shop offer grinders?
Releaf patients can source a grinder directly through the Releaf Shop: the Releaf Puck.
The Releaf Puck is a ceramic 3-part grinder designed for consistent preparation of dried medical cannabis flower. It includes sharp teeth to break medical cannabis flower down smoothly, a ceramic coating to help reduce sticking, and a small cleaning brush to keep maintenance simple.
Key takeaways
- A grinder helps break medical cannabis flower into a consistent texture for vaporisation
- Ceramic grinders are often considered superior because they grind smoothly and reduce sticking
- Releaf patients can grab one of the best grinders available in the UK, the Releaf Puck, through the Releaf Shop
