During the Punk Hazard arc, some giant children are found, and it comes to light that they're actually research subjects who're given doses on a dangerous and addictive drug. When Chopper sees their violent withdrawal symptoms, he comes up with a plan that doesn't seem medically sound (to me at least, with my very limited knowledge of medicine). Namely, he uses sedatives. First Usopp's sleep gas, and then an injection of his own making. My understanding is that withdrawal can be fatal under some circumstances, so Chopper's adamant decision that they absolutely cannot give the children any more of the drug when they're suffering violent withdrawal seems very misguided. Staving off the withdrawal symptoms until they find a permanent solution seems like a viable solution to me. And I'm not sure how effective sedation would be. Was there a better way? Or is this all medically sound?
For an answer, I'd like either a compilation of medical mistakes made in the treatment of the children, or some proof that this actually was medically sound.
