It’s a common misconception that hemp and marijuana are two different species of plant. In fact, They’re just two different names for cannabis, a type of flowering plant in the Cannabaceae family.
While science doesn’t differentiate between “hemp” and “marijuana,” the law does. Legally, the key difference between the two is tetrahydrocannabinol (THC) content. The term “hemp” is used to mean cannabis that contains 0.3 percent or less THC content by dry weight. Psychoactive, or the “high” effect, is not present in Hemp with these trace amounts.
