i dont know what your question is, but this is the point of devolution ... the need can be decided on less of a national level, and money can be used to decide local priorities, which i think can only be a good thing. Over 70% of prescriptions are free anyway (ie they fall into a qualifying category, although they somtimes seem pretty arbitary)
The actual cost of most drugs is huge compared to the price of a prescription, so those still paying �6.85 are benefitting from subsidis from the govt already. Personally, i would rather see the money spent on something else, and people who need prescriptions pay for them. After all, a pre payment certificate is only about 90 quid for a whole year, and you can have as many prescriptions as you need for that. personally i think 90 pounds is a bargain, and those people on a low income get government benefits to help them anyway
