How many Tylenol to get high?

Tylenol on its own will not get you high, taking a lot of it will just permanently damage your liver.

Tylenol #3 and Tylenol #4 contain codeine, a narcotic painkiller than can get you high. It really depends on the person. Also, codeine causes respiratory depression, and therefore it is possible to overdose on it if you take too much.

Tylenol #3 contains 30mg of codeine. Some people can get a high taking 2, some might need 4. Tylenol #4 contains 60mg of codeine, so people can get high from taking just 1 or some might need 2 or 3. Start with one tablet, see how it affects you. If not satisfied, you can try a second, if still not satisfied, try a third.

But taking more than 3 of any Tylenol tablet runs the risk of causing you liver damage. But no matter what do not exceed the maximum daily amount they state on the bottle, I think it's about 8 or 10 tablets total in a single day. Definitely don't take that many at once or more than that in a single day, or again, you run the risk of liver damage.
