I think you mean decarboxylating. That will certainly dry it out and make it easier to vapourize but it destroys a lot of the terpenoids that provide flavour. You only need to decarboxylate when you intend to make edibles. Vapourizing (and smoking) automatically decarboxylate as you are heating the load. I recommend you use a method that doesn't heat it up, you'll enjoy the taste a lot more.
