IIRC, when thc is bonded with a carbon atom, it is quite ineffective at getting you high due to shortcomings of the human digestive system. However in a hash oil product, is the THC "decarbolized"(i think thats the word... im no scientist)? becuase it woudl make sense if it was(as youre using a solvent to extract a chemichal), so then eating hash should get you high.

i would jsut trust erowid though, if erowid says its a go, then its most likely a go.
