The difference between dropping a pill in water, and a crushed-pill in water?

[wynter]

My friend says to crush the pills into a powder, and let it dissolve in water for longer effects of X.

My other friend says he just simply drops the pill in the water, takes around 10 mins to dissolve, and then he drinks it.

Which is better in terms of having a longer lasting trip? I find ingesting a pill hits you hard, but I only peak for 30mins to 1 hour before I crash hard...

I also hear theres a time limit regarding MDMA degrading if left in liquids for long.. what is the time frame?

One last thing, when dissolving MDMA with liquids, which liquids are best to dissolve in? Water? I hear orange juice is better for some reason because of the acids.. and also coke.. Comments greatly appreciated
