When I first saw this thread, why did I automatically think of 'Tomacco'?
(From the Simpsons where Homer used Plutonium as a crop fertiliser and created a tomato with a tobacco centre which was instantly addicting (for those who don't know the Simpsons))
Nonetheless, if that action works, brilliant. But would it be restricted where it can grow? I mean, would it be able to grow in the more arid areas of Africa?
Also, would it still taste as a tomato? It would be great if it tasted great AND helped keep you alive. Talk about killing 2 birds with one stone - 2 methods to keeping you alive.
