A compromise[6] was made that banned exportation of Indian hemp to countries that have prohibited its use, and requiring importing countries to issue certificates approving the importation and stating that the shipment was required "exclusively for medical or scientific purposes." It also required Parties to "exercise an effective control of such a nature as to prevent the illicit international traffic in Indian hemp and especially in the resin." These restrictions still left considerable leeway for countries to allow production, internal trade, and use of cannabis for recreational purposes.[7]
