[Margaret Pilkington]

As Sue says, there are drugs out there which were formulated for one purpose and they were useless for that purpose(for whatever reason.....i.e, they didn't do what they were supposed to, or had other effects that were damaging.etc, etc) but were found to be useful in other areas of medicine...maybe at different doses or formats.
I have nothing at all against MDMA being used for medical purposes...under supervision/prescription, but am against it being taken for recreational purposes......where the person using it has not been assessed by a medical practitioner. In this respect it is an unknown quantity...you just do not know how the person will react to it. The other difficulty with recreational drugs is that they support a whole raft of criminal activities....and because the pushers want to make more money the drug is adulterated with all kinds of substances...which in themselves may be harmful when taken.
