Monkey Drug Trials

The experiment was conducted in 1969 and it was meant to test that animals such as monkeys and rats would look for the injection by themselves of drugs such as morphine, alcohol, codeine, cocaine, and amphetamines, after being trained to do so. The experiment concluded that the animalswent crazy and some of them died.
It is very unethical because no one should treat animals in such a horrendous way and also that this experiment could be tested in another more ethical ways.
