From the book's main page:

For the first time, ‘After the War on Drugs: Blueprint for Regulation' answers that question by proposing specific models of regulation for each main type and preparation of prohibited drug, coupled with the principles and rationale for doing so.

We demonstrate that moving to the legal regulation of drugs is not an unthinkable, politically impossible step in the dark, but a sensible, pragmatic approach to control drug production, supply and use.

The book does not support outright legalization, which it says would be as much of a failure as the other absolutist position, prohibition.

Rather, it wants to regulate the sale of drugs. How? By a five tier system:

Prescription: the most controlling model, this would be an exact equivalent to current prescription models for medical drugs, and some opiate maintenance programmes.

Pharmacy sales: drugs would be made available through pharmacies or pharmacy-like outlets, either on prescription or over the counter. Licensed sales: vendors would be granted a licence to sell specific drugs under certain, clearly defined conditions, on off-licence like premises.

Licensed premises: vendors would be licensed to manage premises where drugs would be sold and consumed, much like public houses and bars.

Unlicensed sales: certain low risk substances could be managed through food and beverage legislation, as— for example — coffee is currently managed.

What does it mean for adult users?

A variety of controls could be put in place to manage adult users. Most immediately, degree of intoxication could be measured; drugs should not be sold to those not in a state to use them responsibly. Vendors might also have to witness consumption for certain substances, as is currently the case with methadone prescriptions in some pharmacies.

Purchasers/users could be asked to produce a licence for a given drug before purchase. Licence acquisition could be dependent on passing a test, ensuring that the licensee fully understands the risks inherent in use of a particular drug. Related training programmes would provide an invaluable opportunity to augment drug and health education for a key target population. Data collection methods tied to licences could provide an invaluable means of tracking and managing individual drug usage.

As to specific drugs:

• Cannabis and opium sale and consumption: membership based coffee-shop style licensed premises

• Cocaine powder, ecstasy and amphetamine: licensed pharmacy models and licensed/named purchasers

• Psychedelics: drug clubs/groups for supervised use in licensed venues

• The riskiest drugs and preparations (including injectable drugs) most associated with problematic/chronic dependent use: prescription/supervised use models

• Lower potency/risk drugs and preparations: a range of licensed sales models
