Does smoking crystal meth really cause it to crystalize in your lungs if you hold it in?

I...
- #1 I Don't smoke meth
-am just wondering how something extremely water soluble would crystallize in a moist place?

Is this more war on drugs lies and disinformation?
I have just always heard this and am curious.
