The name of this “killer” strain says it all. In case anyone doesn’t know, Jack the Ripper was a 19th century murderer in London, the world’s first documented serial killer. Don’t expect anything nearly so violent, but be ready for a creeping cerebral high that’s ideal for creative daytime tasks. The high is decidedly upbeat, with a good dose of both energy and relaxation. This strain works best on depression and anxiety, though it’s also good for PTSD, migraines, and PMS. Jack the Ripper has a lemony citrus flavor and an earthy smell. The THC content averages less than 15%, though some breeders claim levels as high as 26%. While it’s not the world’s most powerful strain, it delivers effective medical relief to many people. The sativa/indica ratio of Jack the Ripper is 70:30, so the high is focused mostly on the head. Some patients experience dry mouth or red eyes, while paranoia is also possible.
