In hospitals, people are often on Ketamine infussions (which to my knowledge is IV) ranging from the elderly in chronic pain, cancer sufferers, terminally ill patients, and the occasional paedeatric case.
In comes in vials (as stated above), but the best way to deal with it is to dry it out and then do whatever you want with it, after u measure it with some accurate scales. That way u can snort it, eat it, plug it (

) or redose to shoot it.
Just to get this straight about ALL pharmaceutical drugs - all drugs that are deemed "dangerous drugs" (ie ones capable of recreational or addictive use) are kept in what is called the DD Cupboard in ALL hospitals, nursing homes, and vet's practices. In hospitals (which is what i have experience with), there are 2 sets of keys to the cupboard (which is more like a safe with a couple of locks on it hidden inside a cupboard). Everyone on the ward at every time knows who has the keys, usually one set stays with the Chief Nurse and the other set with a senior nurse on the ward (usually has to be a permanent staff member with a hefty dose of experience). If someone requires drugs from the cupboard, 2 people must go (usually the person that requires the drug, and one of the aforementioned people with a key). The taking, dosing and administration of the drug is witnessed by both, and both have to sign and attest that everything was done correctly. At the end of every shift (yes, every 8 hours) the amounts of all the DDs left are compared to what has been signed out and accounted for. If too much is gone, or there are discrepancies, the suspected source of the problem is found out and fired (good luck getting a job anywhere else if this happens). Most major public and private hospitals have
very strict policies on this type of stuff, which makes it both extremely difficult and extremely dangerous for anyone to attempt to steal drugs from the DD cupboard. That's not to say it doesnt happen, but it is nowhere near a matter of "poppin down to the hospital" and just chancing across some Ketamine, Morphine, Pethidene, etc in an unlocked cupboard somewhere. You are more likely to get it from a dodgy vet or aneasthetist, or a dodgy pharmacist as they are left in sole control of the catelogue of their drugs.
Criminality-wise: In QLD, K is Schedule 2 (schedule 1 being Heroin, Coke, LSD and psylocibin) putting it on par with speed, ecstacy, GHB, etc in terms of severity of offence and duration of prison time.
Peas out.
