the only 100% way

[stankystank]

the only for sure way to pass a drug test is to drink water and lots of it and pee nonstop that b-12 i heard just makes it yellow again but i passed a drug test in 2 days after smoking some bomb it worked for me it'll work for you

Sorry stanky, but dilution is NOT 100% effective. Substituting a clean sample at the proper temp, is the only way that is 100% effective if you are dirty.
Both methods are linked to in my signature.

How heavy of a smoker are you...?

water only dilutes the THC it dosent get rid of it THC is stored in the fat cells. Tests with a high cut off like at home tests water my work but for probation and outpatient drug tests that are analized by labs arnt gonna be beaten by water alone
