paragraph_text: Cannabis, resin, and extracts and tinctures
  
  The Single Convention is the main international treaty related to Cannabis sativa L. and its products. In its Article 1, the Single Convention defines " cannabis " as the "flowering or fruiting tops of the cannabis plant (excluding the seeds and leaves when not accompanied by the tops) from which the resin has not been extracted, by whatever name they may be designated;" while " cannabis resin " is defined as "the separated resin, whether crude or purified, obtained from the cannabis plant." At the adoption of the Convention in 1961, cannabis and cannabis resin were listed in both Schedule I and Schedule IV.
  
  Schedule I includes substances that are highly addictive and highly liable to substance use disorders, or that are convertible into controlled drugs, while Schedule IV lists "certain drugs listed in Schedule I that are highly addictive and highly liable to abuse and rarely used in medical practice." Schedule IV is a "stricter subset of schedule I, that specifies extra control measures."
