This strain is named after the late Howard Marks, a.k.a. Mr. Nice. Marks achieved legendary status among the cannabis community during his non-conventional life.

To say that Marks lived a very unorthodox life is a bit of an understatement. Having graduated from Oxford University, one of the most prestigious universities in the world, his life took a very different path to what most people, and arguably he himself, would have expected.

Long story short, Marks ultimately got involved in large-scale cannabis smuggling and was sentenced to 25 years in prison. Having served only seven years, Marks, who some described as a “model prisoner,” was released on parole.

To say that Marks lived a very unorthodox life is a bit of an understatement.

After his release from prison, Marks’ wrote his autobiography, which was entitled “Mr. Nice.” It was published in 1996 and went on to become a bestseller, selling over a million copies worldwide.

The following year, Marks stood for election in four different constituencies in the 1997 general election in the U.K. Marks’ entire campaign was centered around one single issue, i.e., the legalization of cannabis.

Unfortunately for Marks, a life in politics wasn’t to be as he received approximately only 1% of the vote. Marks spent the remainder of his life performing his one-man comedy show, writing as a columnist for Loaded magazine, and giving talks where he detailed his life as a cannabis smuggler to captivated audiences.

What Is the Mr. Nice Strain?

This strain by Sensi Seeds was originally named G13XHP. The Mr. Nice strain is a cross between Government 13 (G13) and the Hash Plant strain, so you can see where it got its original name from.
