Health - long term k use & health problems

[adzket]

swim and friends where the first clubbers to be using k within the uk in the 90's use built from a gram lasting all weekend doing bumps to as much as they could get hands on offen at least 10 grams a night at weekends. more resently swim was ding less till last time doing 1 ltr in 10 days it would of been gone sooner if swim did not go out in public. swim is wondering if anything has come out about longterm health problems. they know about the kiddney and bladder problems as well as the legions on the brain thing. a fof has these and one has bowl problems a few others muscular and skeletal problems most of us where young teens when this started and know in late 20's - 40's. swim is wondering if past heavy use of this above any other well used drug is the ression behind most of the group being ill now? any thought's idea's or info of gerneral use to swim only true and proper info wanted thanks.
