I'm definitely not trying to fight - maybe argue a little

- but your comment motivated me to find out if there was any material on the internet that could be safely relied on to indicate where LSD was actually manufactured.
In my 15 minutes of searching I came up with two answers that weren't very satisfying:
Australian Institute of Criminology
They claim basically LSD is imported from the US. Which kinda might have been true in the days when the grateful dead were distributing LSD all around the planet as they toured around. I don't think that's the case any more. Interestingly they reference their statements to the ACC (Aus Crime Commission) but when i searched the ACC publications there wasn't anything on LSD importation from the US.
The
Australian Crome Commission
They really don't say in either their latest report (2011) or the "Other Drugs" fact sheet where exactly LSD is manufactured.
They do however record the ports of embarkation and their research points to LSD manufacture occur in the Netherlands (or at least it comes from ports in the Netherlands). The volume in question could however be easily attributed to that of say Silk Road and there was no reference about commercial importation of LSD (though they don't say that its "small quantities" either).
I have a theory though. there is local production in Australia. In my experience large large amounts of LSD seem to be available whenever you go to Bryon or Nimbin, and usually the product that one comes across is strong, and the blotters that they come on are uncommon else where in the country. Also in my discussion with friends they've remarked about being able to purchase large amounts i.e. dozens of sheets.
That said though for users in the eastern cities of Australia I'd dare say most of the LSD is imported via existing organised crime networks and the local product is isolated/contained to limited areas. This is born from my experience/interactions with dealers who work for major syndicates. Usually I'd be buying H, coke or pills but they'd always say they could get some LSD. this confirmed that the LSD was coming in via the same channels as the other drugs.
Apart from local, organised crime I'd argue the only other source is that is that is imported via Silk Road.
