I searched and only found one thread with anything about smoking with papaya wood. Papaya grow's super fast where I live, but I believe it is quite soft. I have 3 trees that have grown to about 10 feet tall within 1 year of planting, so if it's good to use I'll be growing more for sure. I haven't been able to find anything online to say not to use it...Anybody ever use it or have a good resource saying it's ok to use?
