The Alien OG didn't have much effect on me, but I'm a heavy smoker. I felt like it was weak. But Yavapai herbal has a lot of good strains, Northern Skunk and Kalifia Kush are two favorites.
This strain is awesome! Great for pain relief and very relaxing. I enjoy this in the evenings and on the weekends. If you are looking for a good indica, although this is a hybrid, trust that this is a good strain to check out.
