My condolences to Heath and his family. It's always hard to see a loved one go. As the Trafalmadorians say, "So it goes" Rest in peace, friend. Next bowls for you.
If I still prayed, I would say one for your friend. In stead, I will smoke a bowl out of my favorite pipe for him, and ponder the fragility and inconsistency of life.
Damn man, I honestly feel for you. I don't really know what to say in a situation like this but try and keep your chin up and have a positive outlook, he'd want you to do well in life. Needless to say my next bowl is for you and him, to remember your friendship and respect his passing.
