You could make one I guess. Take an oil from a supercritical extraction (CO2 or liquid N2, or BHO), heat it to decarboxylate the THC so it's active, dissolve it in a small volume of solvent in a little nose spray bottle. You'd have to use a solvent that won't hurt you and is safe to put in a sealed bottle. Ethanol seems like the way to go here. Ether if you can store it in a cold environment like a freezer.

Tincture is Green Dragon if you're old school
Alcohol based THC extraction
Recipe to make your own, I can only imagine what the sativex costs. I've made it before, its not bad but tastes horrible.

I don't know if i'm supposed to post links to competing sites but i don't want to steal the guys words either.

That's actually hash oil or honey oil...something a little different
Much better than tincture IMO, this is usually added to the top of a bowl and smoked.
I haven't heard of taking honey oil and dissolving it in ethanol to make and something you can drop on your tongue.
Much easier to do the other way, BHO extraction is a lot of work.

This is most likely what you would overhear someone at a Medical club talking about.......
but who knows...
where are you spraying? on the skin or in the mouth... If your talking about the skin I would just extract into some coconut oil and rub that on your skin..... gets you ripped! not to mention coconut oil is good moisturizer

I'm aware that it's hash oil. It's also the closest thing to pure THC that most people can get, and it is a much more efficient way to extract than using an alcohol. If you start with an alcohol you need to do more than one extraction or wait a long time to get most of the product into solution. Then you would need to evaporate off most of the alcohol to get it concentrated enough to dose with a spray bottle or dropper. A supercritical extraction is fast, efficient and the end product can be dissolved in an appropriate solvent to dose with a dropper or sprayer. I don't think supercritic extractions are hard, grind the weed up with a coffee chopper, put it in something that can handle low temps, pour in solvent carefully, stir it around a little, filter and pour out, let solvent evaporate, walla you have hash oil.
I forgot to mention DMSO as a solvent earlier. You could then drop it on skin and have it absorb into the blood stream really quickly.

When i made it using BHO, I had a pvc tube, with a hole for the butane in one end and a bunch of holes on the other end for the oil to drip out of. Then I had to heat the oil to get the BHO bubbles to evap out. The leftover product just seemed messy to me. How do i make a thin oil I can actually pour rather than the thick sticky substance that I ended up with. I want to try making something I could put in a vile and pour a few drops out.
Re: alcohol extraction, I got 10g to go into 4 oz of alcohol and about half of that evaped during the process. So it was 10g in 2oz. I'm not an expert but from what I read the exchange takes place once you heat it so no need to do several. The end product was strong but I wouldn't make it again. I favor cold water extraction but I'd like to try making a better oil if you have any advice on getting something with a viscosity like a thick olive oil or a thin honey.

First off don't use PVC or any other plastic, liquid isobutane can start dissolving it or leeching out low molecular weight polymers. PVC is especially bad as it's a chlorinated organic. Not something you want to ingest, especially by smoking. You shouldn't need to heat the extract to get all of the isobutane out, it boils at -11.7°C (11°F). To get a less viscous oil you can add a few mL of cooking oil to the mix before all the butane evaporates, or use a light alcohol (high proof drinking or 90%+ IPA) with a low water content (ideally dry). To make dry IPA get the highest % of IPA you can, then add some Epsom salts that have been baked in an oven at 120°C (250°F) for an hour (add ASAP after baking, MgSO4 is extremely hydroscopic). You can also add the cooking oil or solvent after the butane evaporates but it is much harder to mix. However you do it I suggest gaping oil rather than smoking because you can burn and destroy the oil trying to smoke it. Or you can put it in DMSO and let it absorb through the skin (you'll need to heat it to decarboxylate the thc before using it with DMSO) this will hit you really fast.
If you reflux an alcohol extraction for long enough you can get away with one pass. The problem with the alc extraction is that it can't disrupt the cells very well, while isobutane freezes and bursts cells.
I also have to limit my alcohol intake so even having 10g in 60mL of 95% ethanol is too much. To consume the equivalent of 1g of starting material is equivalent to 15mL of 80 proof liquor. That's a lot when you're supposed to have less than two drinks a month.
I'm planning on doing an extraction soon. If I end up using butane (I want to try dry ice and acetone) I'll see if I can get my wife to photograph the process.
I wish I had the equipment to do a supercritical CO2 extract, but 73 bar is a lot of fucking pressure.

MrEDuck-
I'm gonna have some trim soon and was looking thru the different methods. Tell me if this will work. Put trim in a jar, cover with 90% IPA, shake for 2 min???, filter thru several coffee filters into another jar, pour onto a glass plate, heat on low heat to evap the IPA. Sounds much easier than the BHO method. Anything I'm missing, seems too simple? 2 min shake long enough to collect everything? No heat during the actual extraction?
It also says you can continue to heat and stir to get different textures like glass or budder. the budder seems to make sense cause you are adding air to it but how would it glass up ? the glass texture apparently comes before the budder.
i appreciate any help, tired of filtering ice water thru 25 micron screens. This seems way more efficient and has a nicer looking result.

Samchaser,
You'll get much better results if you reflux the IPA/bud mixture for awhile (since you mentioned heating to help evaporate I'm assuming you have an electric heat source). I'd go for at least an hour. Use the lowest setting that gets the IPA to a gentle boil in a pot with a lid (you want the IPA to boil and then condense on the lid and drop back down). I dont know about the texture, but playing around with how long you reflux for should help you figure it out.
After refluxing remove from heat, let everything cool for about 15-20mins, then filter (a single coffee filter should do for this), evaporate the IPA until you get the desired consistency/concentration.

The main concern in the instructions I had read, i went thru 5 or 6 different sets of them, was that more than a few minutes would release the chlorophyll and give you a impure product. It actually had CAP letters and all not to go over. Wonder what the relationship is to heat and no shake vs shaking and going for 2 min?

BHO is your best best for extraction
BHO = the simplest / easiest/ fastest method of a critical extraction
also.... if youve bho'ed only once and stoped and take what oyu got as solid definition that it only produces the oil you got your wrong
I have a fridge with 6 diff kinds of bho from 3 diff strains
i have a blond sand like hash a golden tacky like hash i have a dark thick maple syrup like hash i have a pitch black gloop of hash
the reason to all these diff results is dependent on 3 major factors
1. strain specific (not every strain produces the same resin)
2. harvest time specific (each strain will produce dif quality of resin through out its life)
3. time waited before extraction was done ( the older the product gets before it gets extracted effects quality and apperance of the resin)

hey hello again
so i did again yesterday much more Lege Artis ))
so i put again 3mL of pure ethanol 99.99999999% in a glass beaker put it in a big pan, not very shallow and as it was standing in the pan i pour 120C hot water and kept string for long time, leave space so u can hold it and stir it.
removed the spray mechanism of a spray bottle, washed it_good and sprayed all the ethanol-710 liquid, take something made_steel over ~50gr of smoking tobacco which
prior to all these i had put him in another pan, put over tin foil and kept in kitchen around 60C till i felt it was dry enough.
so . ..
i spray the "liquid" over the dry tobacco and leave it, dispersed good over the pan, for maybe 1H hhmmm.
u judge it.
now u have a s.tobacco where u roll an one leaf paper, prefer the OCB 1.1/4, there is no odor ))
ps. there is no "smell" of ethanol

something else
what would be
if SWIM would mix hash oil and some CBD drops from a 500mg Concentration liquid where i bought from www.endoca.com
Hash oil has both CBD/THC
u believe it would be a smoother high ??
