Trainwreck is a sativa-dominant hybrid composed of 80% sativa and 20% indica. It is a cross between Mexican, Thai (Sativa) and Afghani (Indica). Even though Trainwreck is sativa-dominant, you can expect a mellow body high in addition to a cognitive high that administers imagination. Patients commonly use this strain for pain, PTSD, anxiety, stress and insomnia. The aroma from this strain is similar to that of ground pepper with a dash of sweet lemon. Trainwreck is also known for being very potent.
