View Full Version : Poppy Seed Opium - Inexperienced - 'Home Made Opium'
[some one I know] tried the opium extraction and this is what he did:
1) Placed 500g of poppy seeds into a 1.5L container with a lid
2) Poured 500ml of methylated spirits into the container
3) Agitated the mixture for about 10min and let sit for another 20min
4) Opened the cap just enough to let the liquid out and poured it into a bowl
5) Let sit in the bowl until the ethanol evaporated away
He used too much methylated spirits so it took a long time to evaporate away. It took so long that he had to put the bowl ontop of a pot of boiling water to help it evaporate.
A brownish resin was left behind that was sticky. The yield was incredible! 500g which usually makes one serve of poppy tea made enough opium for 4 people being smoked continuously for 2 hours.
A pipe at first was used but the pipe got to hot to handle because the opium took a long time until it smoked up. A much better method was to coat a cigeratte with the tar and smoke it.
The High:
This size of about a match head was put into a pipe and smoke. The smoke tasted like poopyseeds and was harsh. Half way through smoking a rush could be felt similar to when the tea peaks. Felt body tingling or as someone else described "when you get excitement in your tummy :)". After the rush felt euphoria and calmness more than you can ever achieve from drinking tea. A while later and after a few more pipes the cigeratte method was used. By placing the tar on the end of the cigeratte and lighting it up the amount consumed was enormous. A large body rush was felt and started to nod out before the cirgeratte could even be finished. The feeling of content was so great just sat on the chair with a half finishsed cigeratte without a care in the world whist half an hour passed away. After the rush finishes (about +30min) a feeling a heavy body load and just plan not feeling very well followed. This was so bad just had to lie down and sleep it off.
The Methylated Spirits:
The problem of the after feeling from the opium made has rasied issues about using methylated spirits for the extraction. The bottle says "96% ethanol". What is the other 4%? Does it evaporate away or could it be harmful when smoked to cause the bad feeling? or is it just 4% water? I know there are other alkiods in the poppy resin other than Codeine and Morphine that can cause bad symptoms, is it just these other alkaloids that were felt? Or perhaps just too much was smoked without letting the first dose finish. Is there any alchohol I can use other than methylated spirits that doesn't have nasties in it? There was isopropyl alchohol but that costs $8 for 125ml whereas methylated spirts costs $2 for 1L.
Sorry for the bad grammer and spelling, it has never been one of my strong points. Also I didn't write a very discrpitive report on the high because I wanted to dissuss the method more which was brought up in this thread Poppy Seed 'Tea' - Exp - Great relief from new prep. method (http://www.bluelight.ru/vb/showthread.php?s=&threadid=172523&r=51). If this isn't the right forum for this to be discussed could a moderator please move it.
Thank You :)

When smoking a product that came out of an evaporated solution, you must know that the solvent is evaporating clean. You can do this by simply evaporating it and see what's left behind. You could be smoking motor oil..
What kind of seeds did you use, BTW?

on extracting raw opium from poppies and boiling it then filtering it to get rid of the crud i has similar effects to what you describe. The body load was awful; cigarettes tasted like sick and i eventually threw up. Would isopropyl alcohol be better for that extraction? why not do it the old fashioned way and slit the heads, takes fucking ages though.

methylayted is 97% ethanol and 3% methanol. Methanol is highly poisonous, they chuck it in there so people don't drink it , maybe thats what made you feel ill.
Homeless people filter there methylated spirits through a loaf of bread which is supposed to get ride of some of the methanol.
Unless you can get some nice low-boiling solvent (ie. lab grade dichloromethane or choloroform in a pinch), I'd stick with everclear. Readily available, cheap as borscht, and considerably less toxic should it not completely evaporate. Which incidentally, it should.
I would imagine that even vodka would do in a pinch. Hmmmmm...
StagnantReaction: a 5kg bag bought at a local wholesaler.
Dave: I thought about using spirits but arn't spirits 40% alchohol? that would leave alot of water in the resin at the end. Also is everclear a type of spirits, I havn't heard of it.
I was reading into how opium is made. They just use water and slowley boil it down to a resin. Maybe there is no need to use a solvent.

Why not use 99% Isopropyl Alcohol?
If you can't find 99% at the drug store then they should have at least 91%.
Either way, it evaporates much quicker. Also, you can tell if it has evaporated all the way by the odor. Plus it's cheap as hell compared to vodka or something.
"Methylated Spirits" sounds like what they call "Denatured Alcohol" here. It's mostly ethanol with some methanol in it as well. There very well could be other junk in it that will not evaporate cleanly. I would not use that stuff for anything...not even a cleaner.
The body load was most likely from the seeds themselves though, sounds like what happens to me when I drink the tea, but worse.
I'd gel cap the resin and eat it. It would last longer, less body load, nothing to smoke (bad for lungs), and no nasty 'tea' to drink.
Water is a solvent like any other, it just has a higher boiling point than others. The only reason that I would advocate using spirits as a solvent is that since they were intended for human consumption they don't have any other junk in it.
If you were to use everclear or vodka, the residual water would just mean that it would take a little while longer to get a dry product.

A kg of seeds in a 3.75L bottle with two liters of 70% isopropyl alcohol was shaken for 10 minutes, let sit for 20 minutes, the liquid boiled down, and a marble sized ball of residue was scraped off. The residue was very sticky, resinous, a dark amber color, and very bitter(alkaloids!). The smoke from a metal hash pipe(similar method to say.. chasing the dragon off of foil) had an unpleasant flavor and produced a scratchy throat.. a smeared cigarette was much more pleasant to smoke. A rice grain sized ball through the hash pipe and a smeared cigarette were smoked in total and a very subtle high was observed(no previous tolerance). Will try again with maybe four or five heavily smeared cigarettes smoked casually with company.
Yeah, heating IPA like that isn't the greatest idea. It has a relatively low boiling point, normally when I want it to evaporate I'll leave it in an open window sill overnight, and it's usually fully evaporated by the morning (happens even faster during the day with an electric fan blowing across the surface).
You might have wanted to shake the seeds a little more, or better yet do 2 or 3 'extractions' with separate batches of IPA to see how much is left over each time. That way it'll be easy to tell how many washes is the most effective.
BTW, is 99% Isopropanol hard to find for everyone else? They have it at the local pharmacy/drug store for really cheap where I live. It's much better to use, it evaporates much quicker and doesn't leave behind any water.

I blended up 7 poppy pods, and used some everclear I had around for an extraction. Ended up with a very dark green liquid, which i let evap. by a window with a fan, and ended up with some real potent smokable 'goo'.
It smoked good, although I can tell it got some of the plant material.. I might find a way to clean it up more.
My local hardware store sells 99% IPA but it costs $8AUS for 125ml.
The extraction was tried again but this time with water. The water was boiled down on a low heat until it become putty. The body load from the Methylated Spirits batch wasn't experianced so I assume that smoking methylated spirits is bad for you.

Here's my experience with this kind of thing:
~2KG poppy seeds were put in an empty and washed grapefruit juice container. I then added two bottles of 99% Isopropanol. I don't have a bottle handy - I don't remember how much is in one, but it was enough to cover the seeds. I shook the bottle off and on, here and there for while. The IPA turned a brownish color. I let the bottle sit overnight.
In the morning, I turned the bottle upside-down and opened the lid just enough to let the liquid out but not the seeds. I poured all the liquid in a pyrex baking dish and left it in the window to evaporate.
After most of the IPA had evaporated (roughly 85%), I started boiling a pot of water. I set the baking dish on top of the pot and the IPA quickly evaporated. What was left behind was a very fluid-like 'goo'. I thought perhaps the 1% water was still left in there, so I microwaved the baking dish for a few minutes to try and evaporate the water so it would be more like a resin.
That didn't work, and I couldn't find a way to dry it anymore, so I grabbed some crushed up wild dagga plant material. I mixed it up with the resin, and it made it much easier to handle and store. I didn't use enough dagga to make a difference in the way one would feel if it were to be smoked.
Smoking the resin provided a light euphoric buzz. I'm not a big fan of it, and personally prefer the oral route. I should have put the resin into a few gel caps to save for when I get a headache. I guess I still can, but I'll be swallowing some dagga plant material....
Do the methanol and ethanol extractions yield a more manageable product?

I did about the same thing as Jaw Clenching..
I used 99% IPA and about a kg of seeds - I wound up with a pyrex dish full of an oil, and deposits of dark brown gooey stuff, and some brown powder - I scraped it all together and mixed it up and then had 1g of dark gooey brown oil.
Tried smoking several hits of it and got really no effect outside the light headedness from holding my breath etc..
So then I ate 200mg and then 400mg - 600mg I ate of this stuff in a day and got absolutely no effect at all..
I have no opiate tolerance and no tolerance to any other drugs either - kinda baffled as to why the stuff was ineffective..

The water batch was weaker but that might have been because it was boiled at to much of a high temprature and killed the active alkliods.
Jaw Clenching: To get a putty you have to keep evaportating the resin down. I also don't recomend using ethonal and methonal (methylated spirits).
Why do you have to use alchohol? The active alkliods are soluable in water and water can be boiled at a low temprature just the same as alchohol. Plus water is cheaper and healthier for you :)

I think next time I'm going to fill a large sauce pan with distilled water and add a small amout of some kind of food-grade acid. Throw in a KG of seeds and simmer for a few hours, separate seeds from liquid and evaporate.
I thought alcohol would be a better choice because it evaporates much quicker than water.
Is anyone going to try an A/B extraction? I'm not even a really big fan of this stuff, so it's kind of low on my priority list. About how many mg of active alkaloids would be in a KG of seeds? How much is a full dose for someone with no tolerance (assuming the A/B extraction yielded crystals :) )?

lumberjack: only some samples of poppy seeds have active alkaloids (codeine, morphine) on the surface--presumably those that haven't been washed well. so there's an element of luck involved in whether you will extract anything useful.

Are you sure it isn't placebo? I have tried making "smokable opium" from poppy seeds about 10 to 15 times and each time it was bunk. You get a brown resinny putty that when smoked taste like flowers, but does shit all.
I've tried 90% rubbing alcohol, boiling down water, everything except ever clear. Perhaps it's the impatience of boiling it down to a putty... maybe if it was left to evaporate in the sun for a couple of days without any boiling you would feel the effects more.
supersnail
09-02-2005, 21:38
boiling shouldn't hurt the codeine or morphine:
morphine decomposes at 250 C
codeine melts at 154-158 C (i'm not sure if this is also the decomposition point, but it clearly does not decompose at <100 C). codeine is light sensitive, but i don't know if that will be a factor here.
i found some solubility info too, that might help someone:
morphine 1g in 15mL H20 (25 C)
codeine 1 g in: 120 mL H20 (25 C), 15 mL H20 (100 C), 2 mL EtOH (25 C)
codeine is especially soluble in dilute acids.
does anyone know if a certain solvent is more selective of the desired alkaloids, ie. if some solvents retain less inert material than others?
i too am interested to hear from more people who have had definite positive experiences creating smokable "opium" from poppy seeds. it seems unlikely that this could work well....
i think this thread might fit better in Drug Basics or Other Drugs. anyone else? i'm new here, and not quite sure how such things work.
It proberly should be in other drugs but I happned to write a trip report with the frist post so I put it here.
What you end up at then end is weak but it is worthwhile for the effort.

Is that reference referring to a certain morphine and codeine salt or the freebase? Does anyone know if the alkaloids present on the seed coatings are in freebase form (my guess is they are). I think adding some sort of weaker acid would help the alkaloids become more stable, and more soluable in polar solutions.
Does anyone have any new information regarding new extraction techniques?
FWIW, I think I have to add this in:
While poppy seed tea reports are variable, poppy tea (from dried whole poppy pods) certainly works, as many of our old-time BL posters will attest. However, instead of making tea with a last batch of pods, I decided that I would grind em up, make the tea, and then boil it down until it reached 'putty' or 'opium' stage.
It turned out to be a complete waste. I got a few grams of the stuff, but it was entirely unsmokable, harsh and disgusting. What would have been 5-6 strong doses of poppy tea was instead wasted as a gross brownish raisin-smelling chunk of pod-putty - which was completely unsmokable (and believe me, I tried.. Oh did I try)
Perhaps an alcohol extraction would have worked better than the water extraction I did via the tea... but I just wanted to put this out there for everyone, because this is a valuable and interesting subject.
Respect The Pod. (And apparently, resepect the seeds within too! :) )

Yeah, I'm almost starting to think that the tea is the only way to go with this stuff. Did you try gel capping the rest of the resin? Do you think it'd be active that way? AFOAF has quite a bit of it left, but they're not about to attempt to smoke that crap again...

Jawclenching: my reference was to the codeine base, and morphine sulfate. i can try to find the link if you want....
i'm curious to know whether the "unsmokable" extracts people have gotten are orally active. i don't know much about smoking opium, but is it possible that incorrect smoking technique is to blame? from what (little) we know about the properties of C and M, it seems like applying a direct flame would damage them. also, both are water soluble, so the water in a water pipe will absorb some of the alkaloids.
some of these last few replies left me a bit disheartened, but i've been doing some reading on alt.drugs.chemistry, and it sounds like a few people there have obtained a smokable product from seeds (try a search for some combination of "poppy seeds" "smoke/ing" and "opium" and you'll find the threads). a FOAF has a bunch of seeds now, and he's planning to try an extraction over the weekend. i'll post results then.

I have used both a pipe and bong with no results, smoking it by itself and mixed with weed. Tin foil method did nothing as well, so I doubt that adding a flame to the psuedo opium is to blame.

here are the details of a crazy dream i had last night:
600g of poppy seeds were placed in an empty, 3L bottle. i filled the bottle with enough water to cover the seeds, and two capfulls of white vinegar. i alternated between vigorous shaking and light agitation for about 10 minutes, and then unscrewed the cap a bit, and strained the liquid into a saucepan. i then put a similar amount of water back into the bottle with the seeds, and did a second wash, again straining the solution into the saucepan. the solution was a milky/brownish color with a suspension of fine, light brown particles.
i turned the heat up to medium-high and let the solution boil vigorously. soon after it started boiling, a brownish scum was visible on the surface of the liquid. precipitate formed on the sides of the pan, and i scraped it off, back into the liquid, every 5-10 minutes. after 30 minutes, all the liquid had evaporated, and i scraped the remaining dark brownish putty off the pan, and squished it into a ball. the consistency was somewhere between gummy and crumbly.
i took a marble sized chunk--about 1/3 of the total product--and tossed it in my bubbler (small waterpipe, but with all the water drained out). it didn't light well, and the only way i could get smoke was by holding the flame on the material the entire time i was inhaling. even then, i only got small amounts of smoke. but, i persevered, and over the course of about 20 minutes, i had converted the "opium" to ash.
the act of smoking this stuff was very unpleasant. it tasted awful, was pretty harsh, and was just plain difficult to smoke. however, i did get a definite, undeniable high. on the few times when i got a decent sized hit, i felt a substantial relaxed/euphoric buzz, similar, but not identical to being very stoned. the strong buzz lingered for 5 minutes or so, and then faded gradually over the next hour, at which time i went to sleep.
the bottom line: the high, while tangible and enjoyable, is just not good enough to justify the difficulty and general grossness of smoking the stuff, especially when drinking the alkaloids in tea is an easy alternative. no regrets about trying it though.
I'd just use acidic water...

smoking seed extract DOES work. You got to understand some common sense though. When you make tea, you are ingesting all the morphine/opiates at once. When you smoke it, you are only doing little increments of that full dosage, one hit at a time. So technically to get the same effect from tea when you smoke, you would have to smoke all of the shit in a very short period of time, which is very bad for your lungs, and impluasible to do.
Just stick with the tea. And why do you call it tea? Opiates are more soluble in cold water. The colder the better. I always use grapefruit juice, and put a pound of seeds in one bottle and a pound in another. Do the shake and wait thing, then strain with the loose bottle cap, then drink it all down as fast as possible. You can repeate the washing/extraction maybe 3-4 times if you happen to come across some really "dirty" (the good kind of dirty, as in the opiates weren't washed off very well) seeds.
Some brands have really washed seeds, and you have to use like 4 pounds to get even a small little feeling. Some brands you can use less than a pound and itch like a bitch.
I find it that the seeds in the bulk bins at healthfood stores are the best.

I agree, smoking the stuff works - but it's not worth it. The smoke is way harsh, and it's difficult to smoke (almost impossible for me to smoke enough to even feel it).

C and M are most soluble in boiling hot water. Stuff tends to be more soluble in a warmer solvent (in fact, I can't think of a case where this is not true, although I suspect there are some...anyone?). The reason you use cold water to separate hydrocodone from paracetamol, or codeine from APAP, is because the solubility of the bad stuff decreases more sharply than the solubility of the good stuff, making the extraction more efficient at a lower temp. To illustrate:
*The numbers are made up. This is just to demonstrate a point.*
Codeine is soluble 1g in 10mL 25C water
Codeine is soluble 1g in 20mL 1C water
and
APAP is soluble 1g in 100mL 25C water
APAP is soluble 1g in 5000mL 1C water

16-02-2005, 19:28
Supersnail is correct.
Regarding whether this is always the case, no it's not always the case but a function of the fact that we are talking about an endothermic reaction. Granted, most reactions are endothermic.
Here's a short explanation for anyone that might care: when you dissolve a solid in a liquid a process takes place that is in some ways comparable to melting. To break the bonds holding the molecules of the solid together you need heat (but remember this forms solvent bonds and the formation of such bonds always generates some degree of heat).
If the heat given off in the dissolving process itself is more than you actually need to break those bonds then the dissolving action is exothermic, that is to say it gives off energy rather than requiring energy. Under these circumstances heating the solution decreases solubility, but that is relatively rare.
If the energy created by the formation of the solvent bonds is less than that required to break apart the solid bonds you have an endothermic reaction - a reaction requiring energy. More heat in this case means more energy, facilitating the breaking down of the solid bonds and allowing more particles to be suspended in the solution.
That was a very rough draft of the principles at work, btw.
