I disagree with Rationahl. I think we have all wasted good bud at some point.
If you have really low quality cannabis, you won't get much product but removing the plant matter will allow a cleaner better high and your lungs will thank you.
This post from my home state gives a good explanation of the different types of hash, and how they are made. Shatter usually involves further processing than oil which results in the consistency.

It will be cleaner, it is natural, and it is natural. I don't understand the butane craze these days.
Make sure you get all of the butane out of the final product (shatter should get it all out) and do the extraction outside OUTSIDE. When you smoke the hash and it starts to bubble, you are literally watching it decarboxylate.
