Hello, As if you couldn't tell my question, I am completely new to marijuana. I'm interested in smoking some to see how it feels and more importantly, if and how I like it. Tomorrow I'm picking up my first bowl, and I guess I am getting a glass one. So this leads me to my first question, what is a carb (I have seen the word pop up all over this message board) and what is it's purpose? Is a bowl without a carb useless? Thanks!
