Tylenol #3's contain the following
active ingredients:
As for the recreational use of
T3's, I recommend against taking more than the
recommended dosage - which is 4 within a 12 hour period.
LD50 for codeine is apparently 800mg (though I wouldn't exceed 500), so you're not likely to overdose on the
opioids, but rather, the
tylenol.
It's worth noting, though, that acetaminophen is not water soluble at room temperature... Codeine is.
If you wish to safely enjoy
misusing prescription drugs, I recommend you add the
crushed pills to room temp. water and pass through a coffee filter. The acetaminophen will be filtered out - leaving you with a bitter solution of codeine and caffeine you can then drink without fear of tylenol overdose.
