Most beginners get high by puffing just 3 to 4 tokes (i.e., 0.2g of weed). Contrarily, regular stoners smoke a full blunt (~1 gram) to get high. Not only that, some prefer to have two full-sized rolls (~2 grams) to get full high. That said, it all depends on the weed quality, amount of THC, and personal tolerance.
