Prescription Drugs That Cause Cancer in Animals

Dr Vernon Coleman MB ChB DSc FRSA

The US Food and Drug Administration insist that drug companies test new products to see if they cause cancer in animals.

Researchers writing in the Australian and New Zealand Journal of Psychiatry studied the carcinogenicity of a wide range of psychotropic drugs.

And here are their shocking findings:

90% of anticonvulsants and antipsychotic drugs cause cancer in animals

70% of benzodiazepine sedatives and hypnotics cause cancer in animals

63% of antidepressants cause cancer in animals

25% of stimulants cause cancer in animals.


You shouldn’t be.

My own researches (first published in my book Betrayal of Trust in 1994) showed that numerous bestselling prescription drugs cause cancer in animals.

There is a list of such drugs here on

The curious thing, of course, is that many drugs are used on human beings – even though they are known to cause cancer in animals.

This is proof enough that animal experiments are utterly pointless.

What is the point of doing experiments on animals, to find out if a drug causes cancer, if you are going to ignore the result? When I asked drug company executives why they do experiments on animals and then ignore the result the universal answer was:

`Well, animals are different to people. You can’t use animal experiment results to judge what will happen when a drug is given to a human.’
