The thing is, that there is really no or only little commercial incentive to study the effects of products that cannot be patented.
That is also one of the reasons why the study of e.g. cannabis for treating epileptic patients, or as anesthesia, has taken such a long time, because once the study is done, you cannot always attribute those effects to your own product, so few will go ahead and sponsor it.
