I still don't know what two wrongs you are talking about?
My point was two-fold:
1. Alcohol ruins more lives and is more dangerous to the bod but is legal because it causes more harm to make it illegal (see 1920s crime rise due to prohibition).
2. If legal, we could punish/help people for ruining lives rather than a blanket punishment the same way we do alcohol (DUI, [Addict] Anonymous, public intoxication, etc)
Most of the dangers of pot come from the fact that it is illegal rather than the substance itself (raises crime rates/drug cartel being the prime example).
If pot was the crime, I don't fault Mills so much as the system. I do hope he chooses to avoid it for the time being though as it currently will derail his career. That said, I'll avoid derailing the topic further.
