If someone wants to kill themselves, the government shouldn't be taking money from you and me to try and prevent the inevitable. As you can see, prohibition isn't stopping anybody from doing heroin - it's actually encouraging heroin use, what with free government-provided needles and everything.
If they only killed themselves, I'd be enough of a callous prick to agree. Addicts to anything, Budweiser included, destroy their families, and pretty much wreck the lives of people all around them.
