Ahaha, I remember in high school the school cop told me about how he busted a kid who bought a quarter oz of oregano. He couldn't technically bust him since it was just oregano so he lashed out on the kid, telling him how fucking dumb he is, and then showed him what real marjuana looks like.
OP, the picture in your first post leads me to believe you are female? If yes, it would really help me to give you an answer if you could provide a photo of the herb in question against a light, fleshy background. Perhaps the upper, inner thigh? PM me
