Masters of Rosin is a gathering of hash heads all over the world. It started in 2018, being 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 products of 64 competing hashmakers and the three best are selected to win the golden, silver and bronze iron.

The week-long event takes place at HQ Club in Barcelona during the biggest cannabis expo in Europe: Spannabis.

You can expect many activities, workshops, presentations, music and of course the Awards Ceremony!

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.
