You will smoke bat shit but not your own minerals leftover from your own body? Numerous studies have been done about the consumption of urine, proving it to be beneficial to ones health. Im not saying go piss in a glass and drink it, like everything else you put into the soil after time it will pass through. Its not like your buds will taste like Eds Heads, they didnt taste like bat shit or cow shit or any other kind of "fertilizer"
