I am Vegan and opposed to the use of animals, in any way, unless there are no other options, we have to live in the World that we have created, iyswim.
I read through the amendment on Animal Testing in Drug Reasearch in the UK. This was published on March 14th.
It is an ongoing dilemma.
Although we do need Animal Testing for drugs that benefit animals, as well. I have a real problem with drug testing for conditions that are lifestyle related.
Many Cancers are lifestyle related, although research does link in together, so one body of research will benefit another area.
Many other conditions are also lifestyle related, that even applies to the lifestyles that are inflicted upon animals in captivity and Pets.
The Vegan and Vegaterian societies have ongoing debates on this subject.
It is a question that you have to answer for yourself.
I totally agree (obviously) with us not needing any more testing of household products or cosmetics on animals, but I'm unsure about medical testing.
I do think that we shouldn't be prolonging life or buying some people time, which isn't popular.
I include my Mother, who has been given radiation treatment for lung Cancer dispite still smoking, so it isn't an "wait till it's one of your relatives" POV.
