Sorry but, when it's say smoke changa in a bong, you refer to smoke in a bong with water ? and in one hit like cannabis ? i mean all the cone in ona long hit till the burned herbs (changa) it's sucked down in the water or like a normal pipe with the burned changa/ash rest in ?

I use a standard water bong for changa (with water in it) and I often take more than one hit. If you can clear it all in one, that would work too!

thaks...so with changa...i want to go slowy...i made a little cone and clear in one hit...then lay back for some time...wait a little....got it ? no...made another little cone...clear in one hit...wait..etc etc ? this is a carefull way to go deep...right ? :-)

Yup, gently light the top, drag it really slow; slowly filling the bong with thick smoke til the changa is exhausted, then let her rip.

Is that how your supposed to do it?

I always just toked and then at the end lift the coned part out to clear the chamber.
It never occurred to me, to fill the bong then suck it up.
I lack bong experience

I take my sweet time with a water bong and have always gotten to hyperspace just fine. I can't smoke a whole bowl in one hit.

My rule of thumb has always been, that if you can ask if you've smoked enough, the answer is to always smoke more... Let that be your guide...

A comfy place to lie down right where you are smoking is a good idea, too.
