My subjective opinion is that cannabis is far more variable in terms of both effects and smell/taste than any alcoholic beverage. Partly because the psychoactive effects come from 100s of discrete compounds rather than just one source (ethanol), but also because there are a ton of aromatics and terpenes in the plant which depend upon dozens of variables -- not just the strain but the ways that you grow, harvest, dry, and consume it. And on top of that, it's being intensively bred and modified at the moment. Intensive genetic modification hasn't happened yet, but I fully expect to see cannabis strains that glow in the dark or contain nicotine (or taste like craft beer) in the years to come.
