can you clarify what you mean by that? do you mean the print-out and repeat script stapled together they give back if you've got repeats. otherwise of course you're not going to get anything but a receipt back, it's not an unlimited ticket unfortunately
Basically, most medications that are recreational fall under schedules 8 and 9 under the poisons act. Schedule 9's are classed as prohibited and you need to apply for a scientific research purposes license to get a hold of anything in that category legally, 9 includes things like heroin and marijuana.
Some milder but still recreation drugs fall under must less restricted categories.... paracetamol compounded with no more than 15mg of codeine for instance is schedule 3 "Pharmacist only", pretty much it's unrestricted and I've never once had any chemist deny a request for an S3. Any more than 15mg of codeine compounded with paracetamol is schedule 4, which is what we know as "Prescription only medicine", any doctor can tend to write just about any S4.
Some things are recreational like dextromethorphan and are only schedule 2 "Pharmacy medicine". The only restriction is a pharmacy must sell it, but it doesn't have to be behind the counter or requested.
Schedule 8 is where most anything fun that isn't simply outright prohibited lies, and Schedule 8 "Controlled Drug"s are tightly controlled. It's mostly specialists who prescribe them. It encompasses most all the amphetamine and uncompounded opioid family. Under the law they must be a certain proportion hand written on a separate S8 prescription form, written in exactly a certain way (to make it hard to alter), and can only contain one substance per script (in contrast to regular s4 scripts can have more than one thing prescribed per script).
In addiction to that, there are various requirements for the pharmacists too. Schedule 8 medications must be stored in a locked container to which only the qualified pharmacist on duty has the key too. Must be accounted for. And usually as I recall, you can not keep the prescription. Once you hand it over, you have to go to that particular pharmacy for refills. If you want to change pharmacies I think you have to ask them to do it for you.
Those are the rules as I understand them.
EDIT: Just in case anyone's curious (I've probably overexplained it already, sorry for that, I ramble)
The reasons the numbers seem a little random is that S1 isn't used for anything and only exists for historical legislative reasons (as I recall), and S5 S6 and S7 are largely for chemicals that are not for direct human consumption anyway.
