Yeah most lung problems are caused by vasoconstriction and inflammation. Cocaine is also particularly toxic to lung cells and it can really mess up their metabolism and overactivate certain genes which end up causing havock down there.From what I understand crack lung is caused by prolonged narrowing of the blood vessels in the lung, the restricted blood flow can weaken tissue which can cause all kinds of things. Im sure inhaling little bits if brillo is also a possibility.
Crack doesn't crystallize in the lungs despite not being particularly water soluble. The lungs have a HUGE surface area and are extremely efficient at absorbing small molecules (at least in vapor form).
Stuff that doesn't get absorbed includes talc, silicon and a bunch of binders commonly found in pills. So snorting pills or IVing them without a micron filter is a sure way to fill up your lungs with a bunch of shit that might stay there for a very long time.
