There's a reason why it's called train wreck, because this strain literally hits you like a train! I can go from sober straight to bring high as fuck! It just comes out of no where. & it doesn't take much either. It has a VERY strong smell, my mom could smell it as soon as she got in my car while it was in a closed container. It gives you more of an up, happy feeling rather than being tired. I highly recommend this strain!
