"The prescription model is the most tightly controlled and enforced drug supply model currently in operation. Under this model, drugs are prescribed to a named user by a qualified and licensed medical practitioner. They are dispensed by a licensed practitioner or pharmacist from a licensed pharmacy or other designated outlet."
Pharmacy model
"The pharmacy model, whilst still working within a clearly defined medical framework, is less restrictive and controlling than the prescription model. Pharmacists are trained and licensed to dispense prescriptions, although they cannot write them. They can also sell certain generally lower risk medical drugs from behind the counter."
Licensed sales
"Current best practice in licensed sales of alcohol and tobacco offers a less restrictive, more flexible infrastructure for the licensed sales of certain lower risk non-medical drugs (see: 5.1 Alcohol, page 100, and 5.2 Tobacco, page 105). Such a system would put various combinations of regulatory controls in place to manage the vendor, the supply outlet, the product and the purchaser, as appropriate."
Licensed premises
"Public houses and bars serving alcohol offer the most common example of premises licensed for sale and consumption. Under this long established system, various controls exist over the venue and (in particular) the licensee."
Unlicensed sales
"Certain psychoactive substances deemed sufficiently low risk, such as coffee, traditional use of coca tea and some low strength painkillers, are subject to little or no licensing. Here, regulation focuses on standard product descriptions and labelling."
