Storing - cwe suspension

[silentsonnet]

swim's pet piranha would like to know if anyone you know can answer this question: how long does a cwe'd opioid last in water stored in the refrigerator?

in addition, and kind of randomly, would adding dye to the water have any effect? especially if it contains other things, such as vitamins/sweeteners...

okay those crystal light mixes. piranha thought it might be a good idea to add color so as to avoid confusion. but piranha wonders if any reaction could take place, especially considering the ascorbic acid (vit c), and other chemicals.

any thoughts? greatly appreciated.
