We have examined the cannabinoid contents of seedlings from twelve strains of Cannabis of known chemical race. Fourteen days after emergence of the shoot those of the tetrahydrocannabinol (THC) type could be distinguished from those of the cannabidiol (CBD) type. The true leaves of the THC type contained a relatively high content of THC and also contained cannabichromene (CBC), sometimes as the major cannabinoid, whereas the CBD type had much lower amounts of THC and no CBC; CBD being the major component. A strain from China corresponded to the THC type but showed some unusual features. Seeds purchased at seven outlets in Britain were also examined. Only two batches germinated by these proved to be of a THC type and resembled the Chinese strain.
我们检测了已知化学类型的12个大麻品种幼苗中的大麻素含量。在芽苗出现14天后，四氢大麻酚（THC）类型的幼苗可以与大麻二酚（CBD）类型的幼苗区分开来。THC类型的真叶中THC含量相对较高，还含有大麻色烯（CBC），有时CBC是主要的大麻素，而CBD类型的THC含量低得多且不含CBC；CBD是主要成分。一个来自中国的品种属于THC类型，但有一些不寻常的特征。我们还检测了在英国七个销售点购买的种子。这些种子中只有两批发芽后被证明是THC类型，且与中国品种相似。
