Talking of similar strains, I can think of such classic breeds as Jack Herer, Durban Poison, and the Ghost Train Haze. These strains do not only produce a similar effect on the smoker, but they also smell and taste kinda similar. For the unprepared smoker, these weeds might even feel like the same thing, but if you are an experienced smoker, you’ll clearly see, feel, and smell the differences between those different strains of weed.
