I noticed tri, you like to argue more then me xD lol
Drug awareness is an important thing to me. Bubba is fully capable of making her own decisions and should do as she pleases, but she (and everyone else) should be aware of what they might be taking and the risks associated with it. I don't want someone to get hurt because they think they're taking 250mg of MDMA and actually take a neurotoxic dose of some other phenylethylamine.
Directly relevant to the above:
1. What is a powerful but relatively safe opiate? Keeping in mind my lack of prior experience with them.
2. What is the best way to perform a CWE?
Opiates are all very similar and their strength is inversely proportional to how safe they are. The "safest" opiate is probably opium wax. It's not very common though because it's neither prescribed as a medication nor demanded by junkies. Of commonly available opiates, I would probably go with hydrocodone as the safest. Oxycodone is also commonly available, but more powerful and thus more dangerous. When experimenting with high(er) doses, be sure to prop yourself up against something to prevent you from laying on your back. A common side effect of opiates is nausea, and throwing up while laying down can cause you to choke and die, Breaking Bad style.
Cold Water Extraction is definitely not the best way to get rid of Acetaminophen in Vicodin. It is however the easiest, so I can see why you'd want to try it. I don't know how much you know about CWE or how it works, so I'll just explain it from a basic level. Hydrocodone (the drug you want) is much more water soluble than Paracetamol (the drug you don't want). So, if you have exactly the right amount of water, all the Hydrocodone will be dissolved while most of the Paracetamol will still be solid at the bottom of the water. In practice, it's nearly impossible to estimate how much water you need to use, so doing multiple extractions is the best way to clear out the most Paracetamol. Since hot water dissolves things more easily, you want to use cold water to avoid dissolving both of the chemicals. Once you understand the basic chemistry behind it, you can see that all the methods of CWE essentially do the same thing and as long as they're properly done they're all about equally effective. Grind up the Vicodin, put it in half a cup of warm water (preferably, room temperature can work) and stir it until no more will dissolve. Put it back in a cold place (freezer) and remove it when it's really forgetin' cold. If you have a thermometer, as close to 32F as possible without freezing is perfect. Strain the water through a coffee filter into a cup. Repeat this process as many times as you like using the scraped powder from the coffee filter instead of more ground pills. Combine and drink the water when done. Twice should be good enough to get most of it.
EDIT: Well, I feel like I just wasted my time explaining that. This wiki article has everything you could ever want to know about CWE.
