AA Critical Sensi Star - 19% THC A crossover between Sensi Star and Critical Mass, the strain combines the power of indica with a citric fruity fragrance that evokes the senses. A smooth toke of the strain will leave you high with a pleasant after taste of a citrus like lemon, kiwi or grapefruit. It is effective in relieving chronic pain, fear attacks, sleep disorders, tremors, spasms and works well as a tranquilizer.
