I think it's fairly safe to assume that the drug trade didn't significantly change over night and that the sources of drugs are largely the same. Which means that a lot, especially of the harder drugs, come from south america. I'm obviously not going to go through the problems the drug trade causes in south america, as I assume this is public knowledge. Of course there is similar problems with manufacturing in the US.
Also I don't think its hand-waving when I base my opinions on the available information. I'm all ears if you can show that drug production has significantly changed (or at least what's is available on SR), that there's a significant overlap, and shift, between buying on SR and buying from street gangs and that this new distribution channel won't have largely the same victors, and therefor problems, as the rest of the drug trade.
Like I said, if someone comes up with a way to locally manufacture smaller amounts of drugs and give the control to the users, than you might have a theoretical case.
