Harmless recreational drug news

James Delingpole, the science commentator who freely admits knowing nothing about science, wrote about the recreational use of drugs, particularly cocaine, last Christmas:

It makes people happy; by and large it doesn’t do anyone any serious physical or mental harm.

(To be fair, as much he doesn't deserve it, he did also list the negatives of cocaine snorting too - but they had nothing to do with health, apart from noting that it "ruined sex".)

Recent news from the US:

In the 24 hours after using cocaine, a young adult's risk of a stroke increases almost sevenfold, according to a new study.

The risk for stroke associated with cocaine use is much higher than with other stroke risk factors, such as diabetes, high blood pressure and smoking, said the researchers from the University of Maryland School of Medicine.

"Cocaine is not only addictive, but it can also lead to disability or death from stroke," said lead researcher Yu-Ching Cheng, an assistant professor of medicine at the University of Maryland School of Medicine.

And yes, I am aware that 7 times a small number is still a small number, but it's not insignificant:

It is estimated that about 13,000 Americans aged 15 to 44 suffer a stroke each year, Cheng said.  "Based on the data in our study, we estimated that about 300 young stroke cases are associated with acute cocaine use each year, but the estimate may vary depending on the prevalence of cocaine use in different sub-populations," she said....

 "Cocaine comes up over and over as being implicated in stroke in people of all ages," said Dr. Richard Libman, vice chairman of neurology at Long Island Jewish Medical Center in New Hyde Park, N.Y.
