Avery chuckled too, but not unkindly. It was endearing that Lyra couldn't smoke, honestly. He liked that about her. It meant she hadn't got up to as much shit as him. Also, he hadn't told her that he used to smoke cigarettes as well as weed because he just didn't anymore. He had a hidden smoking superpower.
"S'alright babe," he said, a tiny bit raspy. "S'not for everyone. How boring would if be if everyone could do the same things?" He rubbed her back, hopefully to help her lungs open up again.
