Thanks to its effects and its high THC level, Pink Tuna is often chosen to treat conditions such as chronic pain, insomnia, depression, chronic stress, and muscle spasms or cramps. Pink Tuna buds have a sweet and sour fruity diesel flavor with a heavy pungent aroma to match. This bud has compact grape-shaped minty green nugs with thin orange hairs and a coating of frosty white crystal trichomes.
