How do you pass a saliva test if you smoked marijuana?

Take a time ..... detection period by Cannibis :(Single Use) 1 hour after ingestion, Up to 14 hours /(Habitual Use) 1 hour after ingestion, Up to 14 hours
or.....Detox/masking solutions. Ihave to take a piss test once a week for intensive probation and 3 saliva tests and I use the service (site called drugtestfriend) that help with a free consultation.Also the give you a formula for passing that you can make from your local store. Once you have the formula you don't have to pay anymore and you can call after for up to 3 years. I call them before every test I have-they take in to consideration the factors at the moment ect..
