Narrow Leaf Drug Type
Narrow Leaf Drug Type (NLD) refers to cannabis plants exhibiting thin, elongated leaflets—typically associated with sativa-dominant lineages and equatorial/tropical origin regions. This morphological classification emerged from early botanical taxonomy distinguishing cannabis by leaf width ratios and plant architecture. NLD plants commonly show extended internodal spacing, taller stature, and longer flowering periods compared to Broad Leaf Drug Type counterparts. The classification remains relevant in breeding programs as a phenotypic marker for tracking sativa genetics and regional landraces. Breeders working with NLD genetics often prioritize trait stability when hybridizing with indica-type material.

NLD classification helps breeders identify and preserve sativa characteristics in breeding lines, particularly when seeking to maintain specific growth patterns, flowering duration, or regional genetic backgrounds. Growers and breeders use NLD phenotypes as visual markers for trait segregation in F1 and F2 generations.
