sorry but the word clarify does not match the profile of someone dumb enough to want to use benadryl recreationally, please reduce the grade level of your grammer and try again

300mg of robitussin is a good recreational dose.
Benadryl is only useful to induce sleep.
Erowid had a good DXM vault.

Well The other active ingredient is Guaifenesin which according to my friend is no real big problem.
