I'll be interested to see what Koopu actually did. The reality is anyone with a bit of spare cash and an active social life is either doing recreational drugs (MDMA, coke etc) or they're just not doing them cos it's not their vice of choice. I struggle to see it as an ethical/criminal issue really. If he's just the bloke who does the donkey work to get some gear for his mates then I really couldn't GAF. Different story if he's genuinely got commercial levels for supply or he's mobbed up or if he's selling P or heroin or something.
And yes, I realise that on some level these drugs are pretty much all emerging out of gangs and international cartels and it's all horrible stuff. I just struggle to blame the average punter who loves a pinger for a situation created by decades of bad law/policy.
