Meth Change the ph level of meth ?

[jjjjooooeee]

I guy I was locked up for while was in for manufacturing. He had 40 years left when I got out . So I figured he knew what he was talking about . But he was saying that if the ph of the meth match’s the ph from your spit . That i’v ing it is the bees knees way better for females than males . I had him tell me how a few times , I don’t remember one damn word he said . Any know how to adjust the ph ?
