Marijuana and Hemp are plant varieties of the Cannabis Sativa species. The main difference between the two lies in the amounts of compounds found in their biological structure. The Marijuana plant has high THC (approximately 5% to 35%) and very low CBD (approximately 10% or less). On the other hand, the Hemp plant contains very low THC (approximately 0.3% or less) and 10% CBD. Marijuana has intoxicating properties (high) and Hemp does not.
