Crystal Coma is a sativa-dominant hybrid that induces deep, trance-like effects. Its name foreshadows the debilitating relaxation to come, a long-lasting calm that shuts off mental overactivity. THC content of up to 26 percent. Crystal Coma’s genetics are long lost, but myth has it that the origins lie in Cheese and Skunk #1. Anxiety, PTSD, pain, and sleeplessness are no match for Crystal Coma’s potency, a medicine that is highly recommended for nighttime use.
