What if you treated the information collected by that variable as really
two variables, one categorical variable indicating zero or non-zero value.
Then the remaining numerical variable could only be analyzed conditionally
on the category was non-zero.

In many cases when you collect data on consumers consumption of 
some commodity, you would end up in a big number of them not 
using the product at all, while those who used the product would 
consume different amounts.
