There’s no better marijuana strain for zooming through to-do lists than Lemon Crack. Born from the union of Lemon Haze and Green Crack, the sativa-heavy strand is known to make people feel like they just imbibed a gallon of espresso, and it went right to the veins. Despite an initial spike in energy that can be a bit intense, this specific herbal variant is also popular for reducing stress, while treating fatigue and increasing mental clarity and focus.
