Many prospective medical marijuana patients are surprised by the number of similarities between hemp and marijuana. However, the resemblance should come as little surprise, since both hemp and marijuana are versions of the Cannabis Sativa L. plant. As we dig deeper into the two plants, we begin to see how they can each play a role in the medical use of cannabis.

One of the misconceptions about CBD hemp oil products is that CBD from hemp oil is less potent than cannabis oil or CBD oil made from medical marijuana. While it is true that the percentage of CBD in hemp plants by dry weight is lower than the percentage of CBD in some specially bred marijuana plants, once the oil is extracted from the plant, this difference becomes negligible.

However, hemp cultivars also grow much faster than marijuana, so while an intensively bred high-CBD medical marijuana strain would take a full season to grow, a hemp farmer can often plant multiple crops a season, creating a more environmentally sustainable and conscious product.

While it has been warned that hemp is a bioaccumulator (absorbs and collects contaminants). It needs to be noted that all cannabis plants, including medical marijuana strains, are bioaccumulators. A medical marijuana crop grown with poisonous pesticides or fertilizers is more dangerous to a consumer than a cleanly grown hemp crop, and with minimal regulations in many medical marijuana markets, there is no guarantee that marijuana bought from dispensaries is healthy to use. Recently in Colorado, there have been a number of recalls for marijuana grown with dangerous, unapproved pesticides.
