I hurt my back the other day and got a bunch of 7.5/750 Vicodin. I used opioid drugs heavily in the past, and still have a tolerance, so I need to take more than the recommended dosage in order to get the desired analgesic effect. Over the course of 12 hours I took 12 pills, which comes out to 9g of Acetaminophen. I did a cold water extraction, but, like an idiot, I didn't look up instructions on how to do it properly. I just did it the way I used to do it, as a stupid youngster. The problem is that I assumed that APAP was completely insoluble in cold water, so I used about two cups of ice cold water for each extraction. But, APAP is not completely insoluble in cold water, and I think that that two cups is enough to dissolve the entire amount of APAP. Now, I did filter some stuff out, but probably not as much as I thought I was filtering, or wanted to be. Should I be concerned about overdose? The first dose was 13 hours ago and I'm not experiencing any negative effects. I don't take it regularly and I don't drink alcohol. I've found conflicting info online. Some people recommend professional help be sought after ingestion of as little as 2g at once. One thing I read said the threshold for toxicity was 15g in a single dose.
 
If by two cups you mean two 8 ounce cups, then that's 472 ml. In 10 degree celsius water, the solubility of acetaminophen around 10 mg/ml. So if the water was no warmer than 10 degrees and the water was no more than 16 ounces, You would have taken around 4.7 grams of acetaminophen. You shouldn't take more than 4 grams in 24 hours. However, if you started taking it 13 hours ago and you don't have any symptoms, you may be fine, although I'm not a doctor so don't take my word on it. If you experienced nausea or vomiting, then you took too much. It could cause your stomach to bleed, not to mention that you may have fucked your liver. If you feel like you have to go to the hospital, then go.
 
Unfortunately, I used two 8 ounce cups for each extraction, which would have been been enough to dissolve the entire 4.5g present in each extraction.

But, I found a Emergency Room flow chart that indicates that I'd be discharged unless I'd taken more than 10g, even if it had all been at once.

I think the 4g maximum is probably meant for a person taking the drug every day for a longer period of time (that's not to say that it's healthy to take more than 4g though).

Thanks for your help.
 
^Good post BoC

OP - you're probably alright, but at your next physical / check-up I'd recommend a liver diagnostic. Your dr shouldn't refuse under the pretense that you're getting Rx'd those 7.5/750's (that's an unfortunately large amount of APAP... More than 2 and you gotta CWE them, and even then..)

Definitely use less H2O next time... Less than one cup would have done all of that no problem. If your CWE is too cloudy, refilter the liquid until it's proper.
 
I know this is a little bit off topic but I have a question concerning CWE. Say for instance the only water you have available is 18 degrees C. Of course more tylenol will dissolve into the solution than if one were to use colder water, and this leads to my question. Will the apap/paracetamol that dissolved into the warmer solution precipitate as the liquid gets cold (say you put it in the refrigerator)?

The reason I ask is because I did some cwe's on panadol with codeine with two cups of warm water so they would dissolve (couldn't be bothered to crush 60-70 pills)and I have been wondering this whole time if I have screwed myself up too. Before I put the liquid into the fridge it seemed that most of it had dissolved, and then when I went to check on it an hour later and it was still partially cloudy so I stuck it in the freezer. by the time a layer of ice formed on the top the liquid was nearly clear.

^I suspect it will come out of solution (assuming max water "absorbency" - crap can't think of the actual word - but the water can only hold so much - if you have water molecules not "holding" any APAP or opiate yet, it will soon enough meaning it won't fall out of solution). Your best bet is to evaporate the water for a while so that you have 1 cup (or less, find out how much you need for your dose of opiate used) and THEN put it in the fridge as this will now work correctly.

So: evap THEN wait for precip.
 
You'll get a crystalline build-up along the sides of the glass container. Use a SMALL amount of water to wash the sides as the water level drops a significant amount. It's also possible to COMPLETELY evap the water and start from square 1. You'll get a better final outcome this way, but it'll take longer. Put a fan or heating element near the containers if available to speed the process up (yeah, waiting sucks, I know haha).
 
The word you were looking for is saturation. If you heat up a liquid you increase its solvency allowing you to supersaturate it. When a supersaturated solution is cooled precipitation will result.
 
So say someone has a few 30/500mg co-codomol, how much water and what temperature would it have to be to get rid of all (or amap) paracetamol , and also how many tablets for a non-tolerant new user of opiates ? If they have never done a CWE, any advice for them ?
