Most prevalent in the Pacific Northwest, Sour Tsunami is a high-CBD marijuana strain with a host of purported benefits. Medical marijuana patients use Sour Tsunami to help with seizures, pain, anxiety and muscle spasms.

First bred in California’s Humboldt County by breeder Lawrence Ringo of Southern Humboldt Seed Collective, Sour Tsunami may have been one of the first high-CBD strains in existence. Lawrence developed this marijuana strain to get off of opioids, which he used to address his severe back pain.

Take a whiff of Sour Tsunami flowers, and you’ll immediately notice this strain’s fuel-soaked lineage, which includes Sour Diesel, NYC Diesel and Ferrari. You may also get notes of citrus, chocolate and earth. Sour Tsunami buds tend to be dense, sometimes with hues of dark green and purple.

Sour Tsunami has little to no psychoactivity. Thus, it’s often not a popular choice for recreational consumers, though it can be reminiscent of cannabis from the 1960s and 1970s, due to its low THC content. If you’re looking for a way to relax with a joint on your porch in the late afternoon before the evening’s activities, Sour Tsunami may be a good option.

With a ratio of nearly one part CBD to one part THC, Sour Tsunami is a popular choice for medical marijuana patients, especially those looking for daytime medication. Originally bred to rid Lawrence of back pain, today Sour Tsunami is used to help with seizures, anxiety, muscle spasms and inflammatory conditions such as arthritis. Sour Tsunami’s high-CBD content also means that it’s often made into concentrates.
