The Sour Diesel is one of the most popular sativas worldwide. Its effects are powerful and energetic, and it leaves almost no sedative after effect or “couch lock”. Many patients use the Sour D in the morning to help wake up and start the day. It seems to work with the brain to create ideas and energy. However, all of this can make it hard to focus on the task at hand. This strain is not for novices — its trance like effect can cause anxiety and discomfort for some. But for many pain patients who medicate primarily on Indica varieties, the Sour Diesel can be a welcome Sativa variety whose high potency proves effective at pain management as well as the traditional mood related disorders. The Sour Diesel lineage is vague and undocumented, which further reinforces the uniqueness of the strain. It is very difficult to grow, and many times has flaky, unimpressive looking buds. But its pungent, distinctive smell and powerful effects more than make up for the lack of bag appeal.
