I parted ways with weed like ten years ago. We weren't getting along so we had to divorce. 
In the last couple of years I tried to figure out what was up with tobacco in traditional and ceremonial ways. And I think I understood something, yet we parted ways. So I don't smoke anything by now. 
If I light a pipe is very rarely with a mixture of herbs to smoke a place and cleanse it. I grow my own tobacco, and I could be using lavender, chamomile and willow bark or cedar wood. But I stay away from smoke as much as I can.
