You must be drug free to buy drugs

It just continually amazes me that they are unable to see that it’s just another kind of drug…

Pub-goers to be tested for drugs
Pub-goers in Aberdeen are facing a drugs test before entering bars as part of a crackdown by Grampian Police.
Officers in the force will be the first in Scotland to use an Itemiser – a device which can detect traces of drugs from hand swabs in a matter of seconds.
The test is voluntary, but customers will be refused entry if they do not take part. They could be searched and even arrested if traces are found.

So if they are free from drugs, then they will be allowed in to purchase and drink alcohol.

Ch Insp Innes Walker, of Grampian Police, said that as a result of the trial period in October “people had a greater confidence that they could enjoy a night out without fear of encountering drugs”.

They really have no sense of irony there, do they?
And so how effective a tool is this kind of exercise?

A total of 753 people were tested on Friday and Saturday nights outside nine venues, which volunteered to take part. No individuals asked to take the test refused.
Mr Greig added that without the device the two arrests could not have been made, and it could be used in the long-term fight against Aberdeen’s growing problem with crack cocaine.

Two.
And the other 751 people, having been stopped and scanned for drugs, were free to enter and consume copious amounts of drugs.
