Opioids Using effervescent co codamol in a CWE?

[isaaccain]

I mean the type that dissolve in water. I figured the reason why it dissolves is because you use 1 or 2 pills (500/1000mg APAP) and a full glass of water, so the solubility is decent, but I've seen everyone on the internet saying that it can be life threatening, but why? Do they do something different to the paracetamol? I've got like 100 of them and they were free on prescription so I'll be super pissed if I can't use them. Also, I figured out a new CWE method, but it takes ages, but would the effervescent tablets work if I were to cool it down to almost freezing, then use an oral syringe with a paper towel over the end as a filter? I noticed that all the APAP clogs at the bottom of the syringe, would that work?
