How to Use the Butane Honey Oil (BHO) Extraction Technique

It’s probably the most concentrated, strongest and most dangerous method of THC extraction – no fancy lab equipment, trade secrets or lengthy trials needed!

Making BHO really is simple and an extremely satisfying way of making weed concentrate, but it’s only for the serious or hobby grower. It can take a lot of dealer weed to make it worthwhile, but you can use trim, leftovers from seed weed or your grow mistakes (snapped, overfed, harvested too early, cured too long, not cured long enough) It’s all good! The best bud does get the best results, though.

THE DANGERS:

Ok, it’s dangerous! You don’t have to be an idiot to blow yourself up doing this. Even the cleverest stoner will sit back and burn one with explosive fumes nearby or overlook something simple. So be careful!

Obviously, it’s butane gas you are using, so smoking a joint while extracting is a no no. This shit doesn’t need a naked flame. Any spark from any source can and will ignite this shit! Even the slight internal spark from a light switch or electric appliance or even metal on metal can do it, so be careful.

I do it outdoors, away from all sources of ignition and so the fumes from the butane don’t get a chance to build up. This shit can also get you high and not in the good way. Some people do it in a garden shed, outhouse or well-ventilated room indoors somewhere, but it’s just not a good idea. It’s great stuff and I’d rather melt my face from inhaling the concentrated product and not the fireball.

There is a massive debate on the purity, safety and toxicity of using butane gas and other solvents to make oil concentrates. Please read up on them before deciding to use this guide. It’s your call!

WHATS NEEDED?

BUTANE:

butane

Couldn’t be simpler. Use as many cans of butane as you need. Depending on the amount of weed, this could be as little as 1. You can do multiple runs of the same material to get it all or cook with the leftovers (citation needed). I personally use 2 X 300mI cans on ½ ounce or 14 grams of pure dried bud. You could use more cans on lesser weed, but the quality will drop. There are a mass of butane brands available. Some will say “near” zero impurities, but I doubt any are actually 100% pure!

Simple test: Spray some butane on a glass surface, window or mirror. If the white residue stays behind, don’t use it! (or only at your own risk)

EXTRACTOR:

You can buy purpose-made, plastic handheld or freestanding lab quality equipment  (like the Honeybee or Wax-Tek scientific glass extractor) that will stop any potential carcinogen causing deterioration from PVC, etc., but I like the Honey Bee. It’s cheap and good quality. Or you can make your own. I’ll not go into that as store bought are the same, and if you’re handy enough to make your own, you don’t need me telling you how to build a simple device!

GLASS DISH:

A square, good quality, high-sided , glass Pyrex dish (immaculately clean) is a must. If it’s not square or clean, you will have trouble harvesting or you could contaminate your honey oil.

WATERBASIN:

Again, anything will do here as long as you can fit your collection vessel inside it comfortably and it can hold hot water. Don’t use anything metal that could potentially cause a spark.

OIL SCRAPER:

The perfect tool here is a single sided razor blade – the kind you get from craft or hobby stores. You will also need a flat tool, like another blade to clean off the residue from the scraper blade.

CONTAINER:

Again, anything you want to use here is fine. It must be non-porous and clean like a petri dish; a lid is also a must!

FILTER:

A standard coffee filter cut to shape will do for the honeybee or homemade plastic versions, you can double up to ensure better quality BHO. The glass visions require a tightly sealed filter material secured with appropriate clamps.

SAFETY:

Gloves are a must; you’re playing with highly flammable, extremely cold materials. Safety glasses and clothing is advisable – plus you get to look like a scientist, in all seriousness please be safe!

OPTIONAL:

Vacuum device. To get the best quality from your end product, you will want to purge the honey oil, I never have but definitely would if I had one easily available

 

That’s pretty much it. Quality lab equipment or homemade device, let’s get started.

1. Pack your material in the device, not too loose, not too tight. You are essentially knocking off the trichomes and liquefying them to oil, but you need the oil to pass all the way through the weed so it will take a bit more than you might imagine. Pack too tight – it won’t pass easily. Pack too loosely – it will pass too quickly! 

2. Attach the filter depending on the device – secure the filter (coffee filter for Honey Bee with custom-made space) 
 
3. Outdoors is best! (see dangers) Using gloves, hold your device with filter end facing collection vessel. Place butane can nib in the designed hole and add pressure (just like filling a lighter).
 
4. After a few seconds, the butane will make its way through the tube (collecting the oil as it passes through the weed) and start to slowly drip through the filter into your glass dish. You will see the butane gather in the dish as a liquid and the oil will have an amber tint. Continue passing the butane through the device until it runs clear. Place used weed to one side and repeat as necessary.  
 
5. When you’re out of butane or sure you’ve used enough, place the dish containing the amber butane in a warm basin of water. The hotter the water the quicker the butane will evaporate. Gently swishing the bowl will increase the evaporation speed. 
 
6. At this point, you have two choices.
Keep replacing the warm water and popping the bubbles in the oil with a toothpick. This will ensure a glass-like finish to the oil.
 
Whip the oil while it’s still soft for a more cloudy, gloopy oil. Reheating the oil will soften it for easier whipping. 
 
7. When all the butane is gone, gently warm the oil in the warm water basin again to soften it and start to gather your harvest with the scraper blade. 
 
8. You’re almost done! Gather your high quality concentrate for storage or smoking – or get ready to purge it. 
 
9. If you have any dry sift, you can add it now and make an oily, jelly-like hash by simply mixing it with the oil. The more you add, the firmer it gets – like soft black! 
 
10. Smoke that shit! You don’t need me to tell you how, but either use a dabber or simply wipe some on cigarette papers & mix with weed. You can also add to a bong, pipe or whatever and enjoy! 

 

Depending on the quality of your raw material, the amount of butane you have used or if you have used the same weed in multiple runs to extract every last drop, you may have enough material left to cook with. I personally always throw it away as I don’t purge my material and it may have toxins or chemicals from the butane left in it.

if you were to use it for cooking, I would heat, decarboxylate or purge it well before hand. If you have enough weed to do a BHO run or don’t worry about the cost, then bake with fresh goods!

Different strains will have different results, but using BHO is the strongest, longest lasting high I have ever experienced with cannabis and the quickest, simplest, purest method i have found to date. I recommend making hashes with the end result. It’s easy, less messy to use and you can customise the quality and workability of the final product.
