I tried really hard to find something fresh and original about this poem, but all I could come up with were the phrases "white and hollow smoke", and "the truth won't set me free". Unfortunately, it's quite unclear what, exactly, the first one means, and the second one doesn't have a strong enough context to really support it.
The rest of the poetic devices were mostly uninspired. Beyond what I previously mentioned, there wasn't anything that I haven't seen already in other poems in excess. The reader quickly becomes bored if he finds nothing but what he's already read.
Try doing a re-write with the same theme in mind, but totally fresh figurative language. Try to keep the poem flowing a bit better, as otherwise the reader will stutter over some of the more awkward lines and generally have a lot of trouble with it.
Overall, unfortunately, it's becoming harder and harder to please the reader with this type of poem. When you log online, these types are all you end up seeing, so you really have to bend over backwards to really impress someone. I'm not trying to discourage you from this realm of writing, I'm simply trying to impress on you how much harder you have to work in this particular genre in comparison to others.
