I believe MJ. like other intoxicants have, could benefit from some government labeling regulation, especially as a "medicine". For example, currently, when visiting retail marijuana outlets/dispensaries, one sees marijuana separated by whatever name the growers/dispensaries care to call it, instead of separating it by THC content, which would be a more-dependable measure. Also, there is no labeling regulation about what chemicals are used in the growing process. Growers could use anti-pest and/or anti-fungal chemicals in the growing process, but give no indication of that when labeling the product. Also, many growers market their product as "organic", but there is no system in place to guarantee that, as one finds in other consumable products.
