Masters of Rosin is a gathering of hash heads from all over the world. It started in Barcelona in 2018 as the first and only cannabis competition in the world that has Rosin as its only category. 

Every year, a panel of professional judges gets together to evaluate the entries of competing hashmakers and the three best are selected to win the golden, silver and bronze iron.

In 2024, for the first time in MOR history, the competition is going international, with editions taking place in New York City and Los Angeles. 

The first LA edition of MOR will take place from November 4th to 10th at Cookies Maywood. The week will be packed with events, seshes and an award ceremony.
