How Long Does Twilight Pill Stay In The System?

Most research only has results for the synthetic drug known as k2. The brand I used was called "twilight". Do you have an idea how long it stays in the system.. I last used on the 8th of January and had a lab test specifically designed according to them 2 detect cannaboids. Some say up to 72 hrs some say a week to be sure. What do you honestly say?
