The deformities in the children were caused by the mixture of the L-form and D-form of the thalidomide molecule. The L-form was safe and worked effectively as a drug, but the D-form was harmful and caused the deformities. Due to modern technology, scientists have been able to isolate and distribute the safe form of thalidomide, and it is now prescribed as a form of cancer treatment.
