Lyric discussion by ktlarney 

Cover art for Bloodshot lyrics by Jack's Mannequin

I agree with Sil here. People feel like they live stressful lives. Weed is an escape from what is a burden to a person. I think the word "high" can be conveyed in two ways here. "Too high", as in a task you feel are out of reach or impossible. "High", as in a escape from life. They go hand and hand, i feel. When somethings "too high" you want to get high.
