Like Sour Diesel, Harlequin is another sativa that is great in treating ADHD. However unlike SD, Harlequin gives you a more relaxed high, while still acting as a stimulant. It is the best of both worlds and works great for keeping you relaxed and stress-free.
And with a 2:5 THC to CBD ration, it won’t cause you to freak out if you’re prone to THC-induced anxiety. You won’t get too burnt out after the high either, so it also has a nice level of sustainability.
