This study uses genetic analyses to assess strain reliability in Cannabis sativa, finding genetic inconsistencies within strains and no clear genetic distinction between Sativa, Indica, or Hybrid types.

This study finds that NIDA-supplied research grade marijuana is genetically distinct from most commercial Cannabis, grouping more with hemp and a small subset of commercial drug-type Cannabis.
