is it rue you can pass a home drug test with salt. ive heard you need about 2 table spoons of salt. but if it is true is there a certain amount of time you have to have the salt in your urine sample.
This is true. I drug test kits are designed to test for THC in urine, so if it is present, you will fail the test. I have never heard of there being any reaction between Tetrahydrocannabinol and Sodium Chloride so I doubt it will have any effect.
