Here's what the MSDS for acetic acid says what happens if you ingest it:
May cause severe and permanent damage to the digestive tract. Causes severe pain, nausea, vomiting, diarrhea, and shock. May cause polyuria, oliguria (excretion of a diminished amount of urine in relation to the fluid intake) and anuria (complete suppression of urination). Rapidly absorbed from the gastrointestinal tract.
Now, keep in mind vinegar is a very dilute concentration of acetic acid you really want to try it then go right ahead but you have been warned just have a bucket ready and a phone with 911 handy.
Basically if you didnt smoke weed then you would'nt have the problem
