DIFFERENTIATING BETWEEN INDUSTRIAL HEMP marijuana AND by Chris Bond Are hemp and marijuana the same or are they different plants? The truth is somewhere in the middle. 56 Maximum Yield T here is a bit of confusion as to what constitutes industrial hemp and what constitutes weed. Is it the same plant? Is it different? Opinions vary from the highest levels of government on down to the common citizen. Plainly and simply put: they are not the same thing. They are closely related, but industrial hemp is not marijuana and marijuana is not industrial hemp. If you come away with nothing else here, remember that. Both plants are members of the same species, Cannabis sativa, but they are not the same thing. Many people, including some in academia, believe hemp is nothing more than just male marijuana plants. However, this is not true. They are genetically different. The primary difference between them is that hemp and marijuana have dramatically different levels of the psychoactive chemical delta- 9-tetrahydrocannabinol (THC). In hemp, THC levels are generally less than one per cent. Legally, hemp is generally required to be less than 0.3 per cent THC as these levels are not thought to have any psychoactive effects. Marijuana plants, on the other hand, range in their respective levels of THC. On average, they have between three and 20 per cent, though many cultivated species have levels of more than 30 per cent. Besides having different levels of THC, hemp and marijuana are grown differently for different market purposes. Some of the differences between the two are also semantical. “Marijuana” generally refers to the flowering tops and leaves of cannabis varieties that deliver some amount of body or head high to the user. “Hemp” often refers to the leaves, stalks, fibres, or seeds of the hemp plant grown for their industrial or commercial use.
