Page scope
Timeline of cannabis history lists dated events in the history of cannabis that other articles describe and cite, with domestication estimates and an automatic list of the excavation sites, historical sources and laws that have pages of their own. Each row repeats the source its article gives for that event. An event is added when an article states it with a date and a citation; a row says nothing that sentence does not say.
Data verification
Record dating problems, conflicts between the timeline and its articles, and the basis of each map point.

Points on the map
A row has a point only where its article names a town, port or site and two gazetteers agree on its position within about 2 km. The point is the gazetteer's place node, rounded to two decimals (about 1 km). Regions, countries and islands get no point.
