Dear Prof. Ajit kumar Roy, fake materials identification sometimes may require professionalism. If you are not used to the real/original one them it may be difficult to identify the fske. To identify and reduce fake drugs in our society, inputs of the regulatory bodies are required, citizens must be educated on the drug, provision of verification code must be made available to confirm the authenticity of the drug free of charge and individual must report any suspected cases related to fake product. Thanks.
