If you want to make things for your own use from woods with known poisons that's fine but if you intend them for sale then remember that you are liable by law as well as any personal sense of responsibility. Personally common sense seems to dictate that if I know that a wood contains toxins and potentially can harm I am am not going to Google the number of instances of poisoning have occurred, I am not going to use it. Too many turners are seemingly unaware that some woods are unsuitable for certain functions and maybe there is a need for some decent articles in magazines and discussions on forums explaining the properties of different woods. Unfortunately we seldom hear of the side effects of a lot of woods only the wonderful properties of them and the traditional, handed down knowledge and wisdom has disappeared as the craft has become more of a hobby and less of a profession. Different people react differently to different woods and to make a generalised statement saying any wood is safe is IMHO irresponsible to say the least. Check out the toxicity charts found in a number of places and see what the actual chemical constituents of a given wood are, don't blithely state that any given wood is safe. I feel strongly about this having had several friends who have fallen ill and in one case had to give up woodworking altogether due to the toxicity of a wood (in his case walnut)
