There's no point in wanting a harsh hit...I'd prefer to get high but not have to think about how much stuff I just coughed up and left my lungs. But if you want a harsh hit (and you don't even know what "ganja" is) I'd suggest a clean ass glass pipe.

Bongs hit you in the face and 9 times out of 10 get you high in one hit. Steamrollers, I don't even have to explain.

Just don't go with blunts or joints if you want a harsh hit basically.
