i watched a interview with rapper Cam'ron talking bout drinking Robitussin is it possible to make lean without codeine, but instead Robitussin?
What the hell is lean? Siz-urp? I believe thats only codeine/hydro concotions. I hear from my dude that siz-urp is actually quite popular in cities with the black rapper type demographic.
robitussin contain dxm, a completely different chemical than the codiene/promethazine combo usually found in lean or "sizzurp". it will make you trip at high doses, but its a deliriant so it kinda sucks overall and its not too good for you either.
