Bongs will deff get you more high. If you're buying OZ and plan to use it for yourself, I would suggest buying a Keef/Pollen grinder. What a keef grinder does is collect all the crystals that your weed has. After a while of collecting the crytals you will have enough to pack a bowl with. And Keef will get you really really retarded high. I smoke keef once and I was just plain dumb. I would forgot what I was talking about mid-sentence and it felt like I was stuck to my chair.
