Which drug presents the greatest challenges to forensic science? why?

Designer drugs

Explanation:

Designer drugs are the type of drug that provides the greatest challenge for forensic healthcare professionals.

Designer drugs are drugs synthesized in order to reproduce the pharmacological effects of regulated substances and hinder global control strategies due to their modified chemical structure. The appearance of these substances, with toxicological information and risks of overdose, which often do not exist, is a major challenge for the government and national and international control laws. For the foreseic science, these substances are also a challenge due to the large number of analogous structures in their composition.
