Marijuana varieties with a THC content of 10-15% can be classified as medium strong. There have always been stronger varieties, especially strong hashish from Afghanistan and the Himalayas. Marijuana, the flowers of the cannabis plant, however, showed values of 10 to a maximum of 15% for a long time. This had different causes. Especially the cultivation methods were not optimal, but also the breeding efforts were not advanced enough. Due to the progressing legalization and the resulting research and cultivation possibilities, completely different values are achieved today. A THC content of 10-15% is in the midfield and, by today's standards, is good, but not breathtaking. However, the THC content is not always decisive for the effect of a variety. There are many other factors involved which should not be neglected. A THC content of 10-15% is a balanced value that is interesting for occasional consumers, just as consumers do not tolerate the high doses of THC too well.
