• It isn't as simple as saying that all animal research should be stopped
• British law requires that any new drug (e.g. antidepressants) must be tested on at least two different species of live mammal
• Such research inevitably results in some degree of pain and suffering for the animals involved


  However, psychoactive drugs allow people with mental health disorders to lead relatively 'normal' lives

• NHA research is useful but also problematic, supporting the statement
