I've never had any problems, it was the only wood I used for the first year of smoking, it was only recently I learned about the poison ivy-oak linage. All of our lump is locally made and they use mango, so I'm smoking with mango and mango. LOL
Being in the Caribbean you should have lots of exotic woods to chose from, guava, rambutan, etc., the rule of thumb is if it bears fruit you can use it for smoking.
