Hydrocodone Sensitivity?

[Mild_Man]

I heard somewhere that hydrocodone is sensitive to excessive heat or light. I think they were refferring to the hydro powder and not mixed in water but I'm not sure. I think in order for it to be affected by the heat it said the temp had to be around 60ºC which is too hot so I shouldn't worry about that. Should I worry about having the powder or mixture in water coming into contact with light though? I was wondering if after I crush my hydros into powder and make all the necessary extractions, how long can I keep the hydro/water solution before the hydro starts to break down? I just wanted to make sure if I make hydro tea in the morning or early afternoon if it will stay the same potency to around or after midnight.

-Sorry for the all the questions lately
