You are welcome.
I should add that this sustained release mechanism has dibutyl sebacate (DBS), which is used to make the mechanism plastic. It is acidic and prolonged use of powder made by simply crushing the beads might cause damage to your sinuses.
This chemical is not soluble to water (0.04g per litre) and also nonsoluble in alcohol (idk about the amount though).
Therefore it will stay on the filter if the alcohol based filtering and evaporation process is done.
It can be done with water too but alcohol breaks that sustained release mechanism totally, which was the reason why Palladon(e) ER or SR (brands depend on where you live) was voluntarily taken off from market in United States when FDA asked Purdue Pharma to do that.
Although this same sustained release mechanism has been licensed to many pharmaceutical companies and even that hydromorphone product is still sold in EU for example and even in Finland where people abuse much more alcohol than in US for example.
More information for that alcohol related breakdown of the sustained release mechanism can be found here:

You could always have that Ritalin with a shot of good vodka or glass of whiskey and it makes it instant release

Of course combing methylphenidate with alcohol is an another issue...
