Serious Lab Grade Acetone Hash!!

This stuff carries over full aroma and taste after extracted..
I did a 5 second extraction with Lab grade acetone its a major difference
from the stuff you get at Home Depot!!!

Night and Day no joke!!!

I let it sit out for 3 days after i extract it and it turns into this!! :yay:

It starts melting at like 85 degrees!.. if i keep it cool it remains hard and easy to scoop for packing the bowl!!!

Impressive...wh@'s the difference with 'lab grade' acetone?

My acteone oil looks almost black...and sticky.

I'm sure you wash for more then 5 seconds

yep

i have done extractions with home depot stuff and can never get it to look or smell like this.. if you open the jar its very fragrant..

i bought the lab grade acetone at a local pharmacy, very pure product leaves no residue at all!

yes it is messy but it can be rolled into a ball if you want.. its easier to sprinkle on a bowl this way though heh..

I used to use acetone in my first few extractions, i found out that it instantly disolved the cannabinoids but also took too much unwanted organic material with it. The quicker the wash the better, longer washes gave no difference exceptin more unwanted material
I did a hot water purge first then let it dry for days, it gave a black, glassly, obsidian like extract that scraped up lighter in color.
I also then purged with adding boiling water to extract and letting the resin melt and disperes into little globlets then let the water evporate away. This give a more budder type extract, that i put down to some excess water in the extraxt that made it more mallatable

Nice job there osirica420, not often that acetone is used nowaday. I would not use it now as i find butane does a better and safer job. Acetone is a nasty chemical, if ingested would cause problems so i would not use if oral. For smoking i believe that acetone combusts to give CO2 and water, so any molecules that escaped a good purge would combust, BUT I DO NOT RECOMMEND ACETONE, it destroys livers (actually it disolves them!)

info on Acetone

Acetone is a normal by-product of mammalian metabolism and is found in virtually every organ and tissue, and in the blood. Acetone can enter the body by inhalation, ingestion or skin contact. Acetone is metabolized by a number of routes to compounds, which are used by the body to make glucose and other products of intermediary metabolism, with the generation of carbon dioxide. Acetone is excreted both unchanged, and following metabolism, mainly as carbon dioxide. The main route of excretion is in the expired air, with very little excreted in the urine. Respiratory excretion is complete within 20 hours after inhalation. The amount of unchanged acetone excreted in the urine increases with increasing exposure concentration and duration, and with exercise during exposure.

Acetone is believed to exhibit only slight toxicity in normal use, and there is no strong evidence of chronic health effects if basic precautions are followed.[14]

At very high vapor concentrations, acetone is irritating and, like many other solvents, may depress the central nervous system. It is also a severe irritant on contact with eyes, and a potential pulmonary aspiration risk. In one documented case, ingestion of a substantial amount of acetone led to systemic toxicity, although the patient eventually fully recovered.[15] Some sources estimate LD50 for human ingestion at 1.159 g/kg; LD50 inhalation by mice is given as 44 g per cubic meter, over 4 hours.[16]

Acetone has been shown to have anticonvulsant effects in animal models of epilepsy, in the absence of toxicity, when administered in millimolar concentrations.[17] It has been hypothesized that the high-fat low-carbohydrate ketogenic diet used clinically to control drug-resistant epilepsy in children works by elevating acetone in the brain.[17]

Butane doesn't sound as safe to me...
Info on butane:

Inhalation of butane can cause euphoria, drowsiness, narcosis, asphyxia, cardiac arrhythmia, and frostbite which can result in death from asphyxiation and ventricular fibrillation. Butane is the most commonly misused volatile substance in the UK, and was the cause of 52% of "solvent related" deaths in 2000.[3] By spraying butane directly into the throat, the jet of fluid can cool rapidly to –20 °C by expansion, causing prolonged laryngospasm.[4] "Sudden sniffer's death" syndrome, first described by Bass in 1970,[5] is the most common single cause of "solvent related" death, resulting in 55% of known fatal cases.[4]

The paper "Emission of nitrogen dioxide from butane gas heaters and stoves indoors", from the American Journal of Applied Sciences, indicates that nitrogen dioxide, a toxic gas, results from burning Butane gas, and represents a human health hazard from home heaters and stoves.

Thanks for the fact check.
I've even seen studies that used suspensions of various drugs in acetone for oral ingestion (fraction of a ml, not chugging the stuff!)

Yeah but what happens when one huffs acetone or spray it...into their throat? Probably just as bad as butane...I would think...lol...

This should answer your question...


Acetone: Health Information Summary


The odor threshold for acetone in water is reported to be 20 parts per million (ppm);
the reported odor threshold in air is in the range of 13 to 20 ppm.

Acetone is a natural metabolism product of both plants and animals, including humans. Those
who consume either a high fat, low carbohydrate diet, are fasting, exercise strenuously, or have
uncontrolled diabetes are likely to produce higher than usual levels.

Health Effects


Absorption/Metabolism

Acetone is quickly absorbed by ingestion, inhalation, and dermal exposure. In two experiments
with humans, inhalation absorption was in the 70 to 80 percent range. There is no data for the
other routes. Absorbed acetone is almost entirely eliminated from the body within a day after
exposure.

Short-Term (acute) Effects

Mild nervous system effects that abated soon after exposure ceased were seen in humans
exposed to concentrations of acetone of 500 ppm in air and greater. Symptoms included irritation
of the eyes and respiratory system, mood swings, and nausea. Accidental poisonings report
similar nervous system effects of sluggishness and drowsiness that were not long lasting.
Only one animal study could be located, which investigated the effects of acetone exposure by
ingestion. Rats were given drinking water containing acetone at a concentration of 25,000 ppm
for 18 weeks. The only effect observed in the rats was weight loss, which may be attributed to
decreased food consumption.

Humans, who were exposed to 500 ppm of acetone by inhalation, experienced eye and nasal
irritation. Levels of exposure below 500 ppm did not cause any adverse health effects. In another
study, groups of students were exposed by inhalation to acetone concentrations ranging from
zero to 1,000 ppm for six hours. At concentrations of 500 and 1,000 ppm, eye, nose and throat
irritation were observed.

Long-Term (chronic) Effects

Workers exposed by inhalation of 1,000 ppm of acetone for three hours per day for seven to 15
years complained of respiratory tract irritation, dizziness, and loss of strength.
In an drinking water exposure animal study, effects on the blood in rats indicating an anemic
condition were reported at doses of 1,700 mg/kg/day.
Carcinogenic (cancer producing) Effects
The one study conducted to investigate potential carcinogenic effects from inhalation exposure to
acetone by workers did not find any excess cancer incidence. There is no data regarding the
carcinogenicity of acetone in any animal studies. Chemicals similar to acetone have not been
found to be carcinogenic to humans. Acetone has been categorized by the U.S. Environmental
Protection Agency (EPA) as a Group D carcinogen (inadequate evidence to classify).
Reproductive/Developmental Effects

Male rats exposed to very high concentrations of acetone in drinking water (3,400 milligrams per
kilogram of bodyweight/day) had increases in malformed sperm and reduced sperm movement.
Whether these effects would impair reproductive ability is not known.

Health Standards and Criteria


There is currently no federal health based standard or criterion for acetone in drinking water.
Mild kidney toxicity was observed at some concentrations in a rat study. Based upon this rat
study, the EPA developed a non-cancer toxicity value (Reference Dose or RfD) for acetone.
From the RfD, DES has derived a drinking water guideline of 6,000 ppb.

The Occupational Safety and Health Administration (OSHA) enforceable standard (permissible
exposure limit or PEL) for acetone in workplace air is 1,000 ppm averaged over eight hours.

At first I was like fuck using acetone but after more research seems pretty benign actually. I know there can be some residue issues. Ketones can be pretty rough on the body especially the liver but looks like it takes a high and consistent 'dose' to cause damage. Still they are a stressor. Ketosis is a real condition where people go on high protein no carb diets where you're body burns fat for energy ala Dr. Atkins.

FDA says no more than 30 ppm residue when used on food stuffs but then again it's the FDA saying it's OK...lol.

Personally would not use acetone nor would I use butane. Only solvents I'd use would be water or 190 proof ethanol.

if you have pure acetone there is no residue.. i did a little test...

just so everyone knows NEVER use hardware grade acetone...
