In response, Pete Guither has an ingenious post noting that marijuana genetics are remarkably diverse, thus creating inevitable consumer demand for a variety of options. Indeed, the war on marijuana and the exhausting, often redundant debate surrounding it have largely obscured the fascinating psychopharmacological diversity of the plant itself.
Experienced marijuana consumers delight in exploring the unique psychoactive properties of particular strains and individual users often develop preferences for certain varieties when they're available. This is especially true with regards to medical use, wherein it's widely understood that some strains are better for specific symptoms than others. Potency is just one of many factors that impact the popularity of a given strain. Sativa strains, for example, are known for being more energetic and stimulating, while indicas are typically more relaxing.
Explaining all of this to people who hate marijuana will surely just freak them out even more, but it still bothers me that the discussion of marijuana tends to present the drug as a one-dimensional substance when, in fact, it is anything but. There are many things worth knowing about this plant that won't fully be revealed and understood until we end the vicious war against it.
