It works great. At US Healthworks
I have used this 3-4 times. It works great. At US Healthworks, Paclab, and a multicare clinic. I smoked last less than 24 hours prior to my test. This is after smoking many times a day for 7-8 years. I eat my share of edibles and even smoke dabs on occasion. I buy the Cherry flavor from Youngs in Federal Way, WA.
