Sasuke had thought about drugs at one point. He thought of drowning himself in the chemical induced state like Mizuki had. It would have helped him forget his current state, his own altered DNA. By now, it would have also let him escape his crazy inmates, who took daily delight in frightening and torturing him. It was probably only Sakura's guiding influence that had kept him from doing them. Sakura was all he really lived for now. He could no longer get to Itachi and all notions of power were now pointless. Some of the caretakers in here were extraordinarily skilled at shutting down people's systems. Sakura was learning from Tsunade still. Sasuke wished he could be out of here, to be with her, but he couldn't trust his own self to not hurt someone.
