Let's say your ready to get high right. Now you have some weed and you have a smoking device. You decide to smoke a couple bowls and then on the 3rd or 4th one you would take a hit and then decide to just go and be high for and smoke the last bit later to catch a buzz. Which is better? Smoking all of it and just ride the high until its over or save a halfdone bowl and come back later to smoke it after you have came down a little. It would just give you a buzz but I'm not sure which is better longterm.
most times when i'm low on weed, i'll pack a big bowl and smoke some of it, then save the rest for when i'm going to sleep
but...i hate it when i decide to save a half done bowl (esp if it's the last of my herb) and when i come back and smoke it, it turns out it was only like 3 hits of half cashed grossness...and i don't get high. so if you save it, make sure you save enough my friend and i would debate this in the past, smoke small amounts all day to stay high, or smoke it all at once to get really high, and therefore stay high for much longer.
I think the most efficient way is taking a couple hits off a bowl every 10 min or so. Just keep that going until the bowl is done and you can almost feel every single hit's individual effects on you. Smoking it all at once and just getting really baked is nice though.
I don't like redosing, as the tolerance of your first session will make the effects of the redose less, and for me, significantly shorter.
