Additionally, Mr. Nice Seeds, founded by Howard Marks and dedicated breeder Shantibaba, represents quality and dedication in the world of cannabis seeds.
Howard Marks’s journey—from smuggling to activism—remains a captivating tale, and his strains serve as a living tribute to his remarkable life.

Howard Marks was a Welsh Oxford graduate who would go on to supply 10% of the world’s cannabis market.

Howard Marks, also known as “Mr. Nice”, was a Welsh author, former teacher, and drug smuggler who achieved notoriety as an international cannabis smuggler through high-profile court cases. He was born on August 13, 1945, in Kenfig Hill, United Kingdom.

Howard Marks was a jet-setting fugitive, a cannabis icon and a leading proponent for legalization. Howard Marks, aka “Mr. Nice,” was a British writer, drug smuggler, and cannabis activist.

Marks studied physics and philosophy at Oxford University while selling marijuana on the side. He became one of the largest drug traffickers in the world, who at his peak in the 1970s controlled a substantial fraction of the world’s hashish and marijuana trade. He was connected with groups as diverse as the CIA, the IRA, MI6, and the Mafia.

He was eventually charged by the U.S. Drug Enforcement Administration, convicted, and given a 25-year prison sentence. He was released in April 1995 after serving seven years. After his release from prison, he published a best-selling autobiography, “Mr. Nice” (1996) and campaigned publicly for changes in drugs legislation.

During the mid-1980s, Marks had 43 aliases, 89 phone lines, and owned 25 companies throughout the world. Whether bars, recording studios, or offshore banks, all were money laundering vehicles serving the core activity: dope dealing.

Marks passed away on April 10, 2016. His life and exploits have left a significant mark on the history of the cannabis trade.
