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 is high but not super high where you will feel too heavy like many of the designer strains out these days! While it’s not the world’s most powerful strain, it delivers effective medical relief to many people. Some patients experience dry mouth or red eyes, while paranoia is also possible. Other negative effects are limited.
