The Global Drug Survey – a good example of invalid data due to bias?

86% of the global population have used drugs in the last year, and more people have used cannabis than tobacco. Almost 30% of the world’s population have used Cocaine in the last year, at least according to the 2019 Global Drug Survey.

This survey asked adults in 36 countries about their use of drugs and alcohol.

According to the same survey, the British get drunk more often than people in any other nation, at least according to a recent

In Britain, people stated they got drunk an average of 51 times last year, with U.S., Canada and Australia not far behind. The average was 33 times.

Where Cocaine use was concerned, 73% of people in England said they had tried it compared to 43% globally.

How valid is this data?

I don’t know about you, but to me these figures seem very high, and I’m left wondering if they aren’t skewed upwards by selective sampling or loose questions.

This report is produced by a private company who sell products related to addiction advice, and I guess their market is national health care services.

Seems to me like it’s in their interests to skew the data upwards to give themselves more of a purpose.

I certainly don’t believe the average person in the UK gets drunk once a week and that almost 3/4s of the population have tried Cocaine.
