@Haley_1990 - yes you can and it is by far the ultimate way to smoke freebase cocaine.
@NightStreaker, in terms of product wasting - this argument is invalid - ppl often misunderstand vaporisation process. The higher the temp the more efficient and rapid is vaporisation. Burning point of weed oil concentrate is also well below target nail temp. Detail is in process of transfer of heat and the trick is to minimise time of contact with heated surface so that there is no more heat transfer after vaporisation - and this is what the nails are designsd to do exacly - oil rapidly heats to vaporising temp and once in vapor form it passes down to bong so no further heating occurs and no burnung whatsoever.
Hence higher the temp the better, see below...
Here is my experiende with crack vaporising and dab rigs. I found it to be by far the ultimate way to smoke crack.
It took 9 months of trail-and-error and a $500 a week habbit but worth every penny.
I tried everything - glass pipe, metal pipe, choreboy, brillo, metal wool, ash, cans, glasses, bottels, etc. - yeah I had some good hits - sure - bellringers even - many of - but nothing prepared me for THIS!
I had the biggest blast hit ever on crack the hit that dwarfed all the hits before it - even the legendary "first" one is now just a fainted memory. I belive I discovered the kilker smoking method that is preatty much on par with IV-coke. It must be as the high I get is very much like ppl describe IV and is 10x stronger than any other smoking method I tried.
So here it goes. Vaporizing!
Sure, it has been done before and verdict was mixed - but here is the twist - vaporizing using the so called dab oil rig for smoking canabis concentrates. The difference with oil bubblers is that you superheat the vaporiser element (nail in the rig jargon) to red hot and than drop the oil that vaporises instantly into a massive cloud that you inhale via your bong.
But it will surely burn your rock, you ask? No, it doesnt - I wont go into detailed phisics to explain why; in leyman terms - cocaine base (rock) is an oil/wax same as cannabis concentrate and it will rapidly heat up and evaporate on contact with heated surface - it wont burn - due to nail design as soon as it evaporates it is no longer in contact with heated elemnt and as you inhale passes down to a bong and your lunghs as pure vapor. The evidence is residue in a bong which is white and clear as the original rock - not even slightly browned by the process.
So what you need is a glass weed bong that can take different glass pipe atatchments and an oil rig nail - it has to be so called domeless kind and I found titanium working best.
you heat up the nail - but it does not need to be red hot - get it quie hot though as hotter it is more rapid the evaporation and bigger the potential hit.
use some sort of a metal tool to lower your rock onto nail - can be thin end of a spoon or a scredriver - I use a dedicatd dab tool which is just a thin metal rod maybe 4in long with one end that looks like a flat scredriver end. start small as it is very potent - try with 0.05g first and then tweak it up to your preference. put your mouth to the bong, start sucking the air in and immidiately lower the rock gently touching the nail so it starts evaporating - you should see bong rapidly filling up with white milk smoke.
The hits are enormous - can't really describe - like having an all body orgasm and like the whole world does not matter and you are the God creator of the universe. the extreme high lasts good 5-15 mins and lingering euphoria lasts for another hour.
I thought I knew all about rock hits - but this simply blown my mind!
The technique is so effective that you can evaporate a whole gram worth of rock in one hit / if you can handle it.
Depending on nail you use there will be quie a lot of residue recycled in the bong - but it is same color and strength as rock you stared with so just scrape it out and recycle!
Vapour is definatly 100% vapor / if you get the size of your hit just right you will inhale a bottle full of white milky vapor and exhale... nothing - all absorbed - and no bitter or any other bad burning taste!
It is also worth noting that this method is also quite efficient - I am deep in so rock isnt really lasting longer (my benchmark is about 1g for 3-4h) but I am constantly in euforia and each hit is big and satisfying - no need to settle for half-hits that only make you cave for more.
You can validate this with a meth style pipe (this is how I came upon discovery - nail rig is just a refiment - but one well worth it!) - but you dont smoke it like meth - that is put the stuff in when cold and apply flame - what you do instead is FIRST heat the pipe until it is red hot and only than drop a rock down while you start to inhale. It will rappidly evaporate into cloud of smoke! The difference here again being you drop the rock on a heated surface.
Enjoy (responsibly)!
