First day of legal sales in Canada is Oct 17 (AFAIK) so comparing to the first day of legal sales in Colordo (1 Jan 2014) is a good idea.
Green line here shows the week of legal sales. Price ran up into it (similar to the action we're seeing in CANNMJ now ) and it didn't stop once sales started.
This is for all the bears in the Canadian MJ space. Watch out.
