What would you realistically use a weed grinder for?

Technically called ‘coffee grinders’ here 😏

Grind pepper in your car to throw the dogs off.

Herbs, lavender, mint, etc

I have one but I don’t smoke weed. I breed fish for aquariums as a hobby and I use it to crush fish food into a powder for the baby fish to eat

If its got ganja leaf motif surely it only has one intended use

I used one to grind pills in the past.

coffee beans... that's it

rock salt

Dead bodies.
