    Dear Dr Jiggens, myself and Dr Robert Austin are researching ASIS’s connection into the Chilean coup. In regards to your book “The Incredible Exploding Man” do you mind if we contact you about your findings on ASIO?
    Kind regards

    Dear Dr Jiggens,

    I am advocating the UK establish a Royal Chartered Commonwealth Cannabis Centre of Excellence to provide evidence on which government institutions can base cannabis policy and to provide economic opportunity.

    I will shortly be presenting a proposal to the Home Office via my local MP Dominic Raab in the Justice Ministry. The legalisation of cannabis is to be debated in the House of Commons on October 12th 2015.

    I’m interested in your research into Sir Joseph Banks.

    But first… have I managed to contact you?

    Yours Faithfully

    Thanks for your many contributions,
    Meant to reach out a few times, most recently during the elections after working with Greg Chipp a lot here in Melbourne.

    On reading your thesis a while ago at least twice and looking at the outcome of Lanai Carters endeavors including her lawyers work around the Australian constitution specific to c 109, looking at Canadians suing their own government and winning per their own rights article 7 in their constitution (the right to liberty, justice and the right to not be fucked with) , and returning last week from Amsterdam and Berlin, I still reflect on the Sackville Royal commission you referenced in your thesis.

    Specific reference to Australia misinterpreting and incorrectly enforcing the single use act being incorrectly interpreted for personal use and trafficking when it was really about trafficking and NOT personal use. Of course SA shot down the Sackville recommendations and instead began nationally the lowering of the benchmark of what trafficking is, and especially here in Victoria introducing 7 hidden new laws on contributing to trafficking making everything from books, emails, websites punishable by up to 10 years in prison and increasing the distances around school and changing the laws from being sold to kids near a school to anyone within ½ km all in a bill against Cannabis when the word Cannabis was never in the bill in Feb 2016 ( ) in the Victoria DPSA Bill 2016

    And I guess worse, since the 2015 showing 91-94% of Australians support medical Cannabis ( began the process of changing the definition of what Cannabis is form a plant to a suite of products none with THC above 3%.

    Now of course the legal state licenses of hemp growers have been told (per the ODC) to cull their hemp if it is above 1% and less than 2%, as that is now be classified as Cannabis also. Then I see you reference QLD recently, but I did not see reference where they have redefined Cannabis also to include synthetic opioids like fentanyl that killed the singer Prince recently. This not because Subsys/fentynal is Cannabis but per the bill they want to, “Treat anything that acts like Cannabis to be called Cannabis”.

    So Mr Jiggens, based on all of this and with Amsterdam considering suing their own government as are Germany, do you see any fruitful direction for a constitutional challenge here eg. based on c 109, Sackville etc. Otherwise having the richest PM in history and 2nd richest parliamentarian, (only 2nd to Palmer) and married to a chairman of a biotech pharmaceutical company we otherwise have a tough struggle.

    Thanks in advance

    Kind Regards

      Thank you for this lovely letter and sorry I have taken so long to reply. Yes, synthetic cannabinoids are now cannabis in Qld too, and Clinical Guidance: for the use of medicinal cannabis products in Queensland allows Dronabinol—synthetic THC (Marinol®)  Nabilone—synthetic analogue of THC. These were available before. No mention of fentynal. My fb page John Jiggens has the latest developments up if you want to read that.

    Dr John Jiggens also presented at a Medical Cannabis Moretorium in 2015. I was pleased to be asked to speak on the day representing a new social movement that has blossomed into a progressive social establishment funded by industry partners here and overseas. Women For Hemp has a vision for the future of a promising new industry in Australia and can be found on Facebook.

  5. Peter Rainne says:

    Are you still with Queensland University?

  6. Ann says:

    Question, did you write a book recently titled Game of Mates? If so where can it be purchased. Thank you.

  7. Lawrence Hamilton says:

    Hello Dr. Jiggins. I am freelance journalist who has returned after some time in Alaska and am now recovering from a back injury.

    I am interested in working as a journalist covering the changing mores around the cannabis industry and the changes coming with the possible legalisation. There is quite a bit more to than that but I have come across your work and you seem like a man I would like to talk to and I am interested in asking you a few questions (can be off the record) and ordering some of your books.

    Thanks a lot and I look forward to hearing from you.

    I am trying to contact you to buy the Incredible Exploding Man. Your email doesn’t seem to work 1 what’s the best way to reach you?


  9. Amy says:

    Dr Jiggens

    My previous comment appears not to have been submitted – I am looking for a copy of your book called The Incredible Exploding Man. The email I sent seems to have been returned to me – what is the best way to place an order?



  10. Wayne Grogan says:

    Dr JJ, we spoke a few years back. I want to buy ‘The Sydney Connection” & The Killer Cop & Incredible Exploding Man. If you provide details inc postage costs I’ll transfer funds. Regards Wayne Grogan.

    Also interested in money laundering through early 70’s via rising property values around Byron Bay area.

  11. steve johnson says:

    I would like to purchase The Incredible Exploding Man, Marijuana Australiana and The Sydney Connection. I would like the paperback but would also like a word file so I can read on Kindle which makes it easy for me but I guess PB version in all that is available. Thanks fine – can I have a price and pay via card online?

  12. Stephen Taylor says:

    Dear Dr Jiggans, I just read your article “The Killer Kop” written in 2010. In the article you make many quite definite statements that Fred Krahe did this and that or killed whomever. Unfortunately you don’t explain why you are stating those things.
    Where can I go to find some proof or even some evidence pointing to your written beliefs?
    Disclosure… Frederick Krahe was my Dad’s first cousin.

    • John Jiggens says:

      Steven, There is a lot of literature on Fred Krahe. I first read about him in the book The Prince and the Premier by David Hickie. My books on him are The Killer Cop and the murder of Donald Mackay and The Man Who Knew Too Much and in those I suggest he organised the murder of Donald Mackay while working for the Nugan Hand Bank. You can order those books on my web page. Evan Whitton is the source of the claim that he also was responsible for the murders of Don Ferguson and Juanita Nielsen, altho the latter claim was previously made by Tony Reeves. Evan Whitton made that claim in a magazine called Justinian. If you were to google Evan Whitton, John Jiggens, Justinian, Ted Shackley, Juanita Nielsen, Don Ferguson, you would almost certainly get the article. When Evan died we did a tribute to him on our news show. I interviewed Quentin Dempster about Evan, who I venerated as one of the most significant journalists of the generation before me, and Mia, our EP, found an interview on the radio with Evan where he spoke about these matters. Tony Reeves claimed that Krahe organised the murder of Juanita Nielsen in an interview with me but I can’t remember what book of his it was in. He also repeated the claim about Don Ferguson in that interview and added details I couldn’t check. Both Evan and Tony are dead now. I remember Tony telling me Krahe’s sisters were upset by Tony’s claims and threatened to sue him, but I don’t think they ever did. I remember Tony was unconcerned about their threats and treated it as somewhat of a joke. The interview was thirteen years ago so it is difficult to recall details. I have met another member of your family and it is awkward. People love their family and don’t want to feel bad about them. Freddie could be charming. I have met people who told me Roger Rogerson could be very likable too. They have immunity from the justice system and they develop a sense of impunity. Because they are the law, they think they are above the law. I don’t understand them.

  13. Look at enjoyably up something with a segment win.

    Hi John
    I have just had a squiz at Imre Salusinszky’s new release “The Hilton Bombing-Evan Pederick and the Ananda Marga” You and your book “The Incredible Exploding Man” get a mention pp287-89.
    Do you have anything to say to him?

    • John Jiggens says:

      I may one day, if I get round to it Phil, tho I do get a good laugh to think that finally, after three decades, Evan has found someone else who believes him! I guess there is one born every century! Lovely to hear from you. Hope all is well tho we are both old now! Lots of love!

  15. John Goopy says:

    Dear John,
    I am enjoying reading your thesis. I have a particular interest in the illicit drug trade in Qld, 1935-1950. Aside from your very good work, is there aby source material which you could point me towards?

    • John Jiggens says:

      I can’t remember what is in my thesis, but I have rewritten The Reefer Madness Campaign of 1938 twice. The most complete version of ‘The reefer madness campaign of 1938’ on Queensland is in the book “Sir Joseph Banks and the Question of Hemp”. It is the last chapter. Apart from that, I recommend you search Trove and it’s digitised newspapers, available on the national library of Australia website. In terms of state archives, try and locate the correspondence files of the Government Botanist, which will be in the Dept of Agriculture archive files.
