East Coast Sour Diesel Strain — THCA Profile, Effects, and Where to Buy
East Coast Sour Diesel — ECSD — is the New York phenotype of Sour Diesel that many connoisseurs argue is the truest expression of the line. Most accounts place it as a Sour Diesel × Mass Super Skunk backcross. Premium THCA hemp cuts test 20-26%.
Lineage and origin
ECSD (East Coast Sour Diesel, sometimes East Coast Sour D) is a New York-bred phenotype/cross of Sour Diesel, most commonly cited as Sour Diesel × Mass Super Skunk. The cut became a holy-grail strain in the New York medical underground in the late 2000s and early 2010s, where it earned a reputation for the loudest diesel aroma of any commercially available cultivar — buds reek through multiple sealed bags. Many connoisseurs argue ECSD captures the original Sour Diesel terpene profile better than the West Coast cuts that bear the name today.
Terpene profile and aroma
Caryophyllene leads, with limonene and myrcene rounding out the load. The aroma is a knockout: piercing diesel and lemon-skunk over an earthy fuel base that lingers on clothing for hours. Buds are loose, fluffy, and laced with bright orange pistils.
Effects in plain English
