I have to take a piss test every week for probation and still smoke daily (also 1 hair and 1 saliva). And I use the site called drugtestfriend .They sell a formula(29.99) that I can make my own detox drinks (masking) at home and provides a counsler to help me. 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... I practiced any and almost everything before to use them and was skeptical at first but there systems work for me more then 6 times. Also they help with a free consultation-piss, hair, saliva and blood.
