Sorry, but since society will have to pay for your living expenses if you become a public charge as a result of a heroine habbit, it has a right to prevent you from doing heroine.
I had a heroine habbit once,and I'll state from experience that,should any young man be contemlating a heroine habbit,contemplate one that isn't redheaded. Fun,but expensive. And society most assuredly didn't pay for that habbit of mine-I was stuck with the bills,and they weren't small ones.
