"I want to love you but I better not touch"
Sounds to me like she's hurting him in some way... Possibly leading him on, cheating on him, or just plain not interested. Either way he seems to be obsessing over her and that's why she's poison to him.
"I don't want to break these chains"
Even though she's messing him up, he doesn't want to give up on the thought so he's stuck in a dilemma. Also, this line of the song pretty much nullifies the idea that it could be about drugs or alcohol, because he would definitely want to break the chains
