I hate to break it to you, but ingesting baking soda doesn't make any difference on a drug test. It will make you vomit though...
I did meth 1 1/2 days ago, yesterday did the baking soda thing but vomited. I took the test 4 hours after I took baking soda. I failed!!! Trying today hopefully not to vomit and make the 2 hour mark. Why didn't I pass? Can I do the regiment again today?
