What a bunch of crap, you might be thinking to yourself, nothing cures all these deseases. But, if you understand how cannabis works you may think again.

That's a very dumbed-down explanation, it make more sense when you listen to the science as decribed by Dennis Hill, the biochemist who cured himself of prostate cancer. Solely by digesting cannabis oil and cannabis butter initially.
So, this is the list of diseases that cannabis can help with.
