Who gives a shit? We were'nt all meant to be high flying jet-setting executives. If I want to slowly destroy my brain with opiates, as long as I still hold down a job to pay for my lifestyle, who's fucking business is it but mine? We're all going to die anyway, mind your own and I'll mind mine.
Oh, wait, because drugs are illegal and opiate replacement therapy is hard to come by, it becomes society as a whole's problem. You've got junkies scheming for money, unable to hold down jobs, and just generally being pieces of shit. But all this can be alleviated if this whole 'prohibition' and 'abstinence' trash was replaced with something more modern and progressive. Prohibition failed a very very long time ago. Rather it's alcohol or opiates, it really doesn't make much of a difference. As an interesting side note, alcohol prohibition was modeled very similar to opiate prohibition is now, what with doctors being able to prescribe alcohol and such.
