不可能有的，化学阉割是有时限的，时间过了那些人可以再出来作案，而且化学阉割副作用十分大，就好比慢性自杀，所以大多数国家都不会把化学阉割列入法律
It can't be. Chemical castration is time-bound, those people can come back, and the side effects of chemical castration are so high that it's like a chronic suicide, so most countries don't include chemical castration in the law.
