Oyo house of assembly identifies 500 indian hemp joints

I think there may be a mistake here. "Oyo House of Assembly" is a legislative body in Nigeria, and it's unlikely that they would identify 500 joints of Indian hemp. Indian hemp is a controlled substance in Nigeria, and it's illegal to possess or sell it.

Could you please provide more context or clarify what you mean by "identify 500 Indian hemp joints"? Are you referring to a different context or organization? I'd be happy to help if I can.
