Rats on methamphetamine listen to the Prodigy

British universities have spent £10m in the past ten years on animal experiments into the effects of illegal drugs, according to activists who say it is cruel because such drugs are "luxury" items people use by choice.

The British Union for the Abolition of Vivisection produced a report which includes data released under the Freedom of Information Act and says Cambridge University has received £1.6m over the last decade for such tests from the Medical Research Council.

The report says one study looked at how chemicals in cannabis caused rats to get the "munchies" like human cannabis smokers; another involved playing the Prodigy and Bach to rats high on methamphetamine - leading to a reprimand from the Home Office for going beyond the original research licence.
