Ive been told by a club owner and a maker of serious butane extractions. The person who makes the butane extraction told me that the butane in the can was not fit for human consumption, was never intended for the way we are using it. He went on to further say that there was only one place to get human grade butane. That place is in Texas. He might be wrong but who knows. If you want a cleaner product this higher grade should be used. He went on to say that there are lubricants used in the cans. The lubricants are what help the butane to move through working metal parts. He told me that these lubricants are what prolonged exposure to is very bad when you smoke them. Smoking bho daily might not be very safe.
He might be wrong, but until more is known ive quit, along with many of my friends. In fact we all have now quit smoking bho.
Im not trying to scare anyone or highjack this thread. Im simply relaying what ive been told.
If you are starting with 100% clean butane then im sure your extractions are the best Greywolf. You know what you are doing.
Have you heard reports of anything added to canned butane?
You've been mislead by the club owner and I would advise accepting nothing he says on any subject, until you can tell if he is just ignorant or has a secondary agenda.
There is no need to add any lubricant to butane, because it is a simple alkane hydro carbon that is its own lubricant. There is no difference between butane, oil, or paraffin wax, other than the number of carbons in the chain.
I don't advocate smoking anything, as it is hard on the lungs and produces pyrolic elements that can be carcinigenic. If you want to inhale it more safely, vaporize the oil.
I use canned lighter butane if I need to, and stick to long proven brands. May I put butane in general in perspective?
It is a simple alkane, the smallest of which is methane gas and is one carbon molecule, with its four bonds occupied by hydrogen molecules. It is actually safer than your own farts, because your farts are a mixture of odorless methane, and sulfur containing mercaps.
Ethane is two carbons with the rest of the bonds occupied by hydrogen, and so on up through the simple alkanes. Propane is the next in the line of simple alkane gases, followed by butane, which is a gas above around the freezing point of water and a a liquid below that. The byproduct of burning any of those four alkanes is C02 and water vapor.
As far as production, major refineries get all four of the first gases from raw crude, simply by heating the crude and fractionally condensing the gases as they boil off. They then run the gases through a reactive bed desulphurization process and produce a commercially pure 99% product. The principle impurities are the gases that are closest to n-Butane, which is Isobutane, propane, and cyclopropane. If you will look at the MSDS sheets for all of those ingredients, you will see that they are not toxic at any levels you are apt to encounter them in exctract.
The thing that they do add to n-Butane in a pressurized can, is propane. They do so because at freezing temperatures, n-Butane has no gas pressure, despite it being used as a propellant in food containers.
Butane that is used as a fuel gas, may have ethyl mercaptans added for leak detection, because even though butane does have a slight sweet petroleum odor, it is subtle and ethyl mercaps can be detected at levels below 3 parts per billionth. Ethyl mercaps taste and smell like rotten eggs, which makes that type of butane unsuitable.
Lighter butane has additional refinement to remove any remaining trace paraffin waxes, which clog the small orifices of quality butane lighters. Paraffin in the brands typically used for extraction are below 15 parts per millionth, and are not toxic at those levels.
As far as only butane from Texas being quality, you know that everything is bigger and better there, but R-600, 99% CP, 99.5% Instrument grade, and 99.93% are also readily available in Oregon. They are a damn sight cheaper in Texas.
