If you dilute, you dilute the lot. It will depend on the cutoffs on the test whether you show positive for the metabolites that are 'supposed' to be there.
sarah louise Reviewed by sarah louise on . Certo and pain meds I was wondering ... I take pain meds and I have a script for them and I smoke occasionally. If I do the certo trick will it also block the pain meds or just the THC? If I have to take a drug test for my doctor he has to see that I am taking the pain medication but I do not want him to find the THC in my system. I only smoke maybe 4 hits a month. Rating: 5
