Trainwreck smells exactly like pinesol to me. Big favorite of mine. Heavy eyes, tingly body stone, and that hazy sativa rush are what the high is like. Trainwreck also has very very tiny (circumference) stems and a distinctive leaf shape. If yours fits that bill it is most likely trainwreck.
This is what I tell peeps...very intense and unmistakable...and while Pinesol has a decent pine note to it TW is more like a solvent.pinesol
