Undercover GHB operation: A real case

You are working an undercover operation where you have been buying drugs from "John Doe" for approximately one month. The goal of buying drugs from John is to catch the "bigger fish" so you want to continue to establish a relationship with him to locate his buyer.

You were introduced to John Doe through your informant, Kay Smith. She has been working as a confidential informant with you for over one year and the information she has been providing to you have proven mostly valid. She contacts you recently stating that she has been talking to "John Doe" and he said that the next time you meet him, he is going to put a "roofie" in your drink and rape you.

As an undercover agent, your safety has now been compromised based on the information provided to you by your informant.

How do you respond to this information you have received?

What would you do? What effects do GHB, "roofies" have on a person? How is a roofie administered?
