Sieh Samura

Sieh Samura is the CEO Yamba Market and co-creator of Purient Bedroom Cannabis.

An Iraq War Veteran and early Massachusetts medicinal cannabis patient turned rights advocate and conscious entrepreneur, Sieh also known by his nickname “Chief”, Is an original and fierce advocate for cannabis consumer rights  in The Commonwealth of Massachusetts and nation. 

Chief’s advocacy included the first televised home delivery of cannabis in Massachusetts (2016) and encouraging effective and socially equitable policies, strategic public testimonials and targeted education to Governmental bodies, like then City Councilor and now Congresswoman Ayanna Pressley, former Boston Mayor Marty Walsh, Former Boston City Councilor Kim Janey now Current Boston City Mayor, MA State Joint Committee on Cannabis, and numerous others. 

His historic private cannabis club and delivery services listed on well-known platforms like Weedmaps and Leafly, predated just about every licensed cannabis operator in the region, and served the severely underserved regional cannabis consuming community prior to the full roll-out of licensed adult use establishments during what he terms as the “Massachusetts Medical Marijuana/Cannabis Interregnum (when MA citizens were encouraged to get mmj cards but there was very little to no support for those same citizens to obtain needed products, necessitating private unlicensed services, and resulting in exponential growth of unlicensed market. 2012-2017)”
