If your tablets are just generic 8/500 co - codamol with no colourings you should be looking for a water - clear solution : even when well filtered this 'clear' solution will still have apap dissolved in it - I personally would just filter and re filter until you get this as any visible 'cloudiness' - providing you are using the kind of product I described above - will in all likely hood be undissolved apap, and using my cod logic my first acid test when using this procedure is to at least remove all visible paracetamol particulates.
Use (non-flavoured) coffee filters for this, and refilter if there is any hint of cloudiness or visible contaminants in the final solution. It should be clear, but distinguishable as a codeine suspension due to the foul smell and taste.
Bluelight members can argue the toss of the semantics of CWE all day - they have for the last decade and a half, so, as part of your welcome to the site Jaaamy - why not give our search engine a whirl where you will find an INFINATE amount of threads that have discussed this over the years, and through which you can get a much wider perspective on this than PotatoMan, myself or the other members can give in this discussion alone.
