Somehow I envision this as being written directly out of Naoka's memories. Probably not (she's probably too young anyway), but that's what I imagine.
Re: paint thinner and marijuana, the situation in Japan is ironic given that Cannabis is canonically a sacred plant in Shinto, and the long standing tradition is to burn it on Obon (yeah, the dead are visiting you when you burn a bunch of psychoactive incense around the house... Totally coincidence - though now you can only legally burn stems, that's a modern restriction). Yeah, I think there is a lot of bullshit covering up the true historical use of cannabis in Japan. In any case, paint thinner is a much less safe idea, as are amphetamines, which are #1 illegal drug of choice in Japan.
