Teens in South Africa have found a new use for efavirenz (brand name Stocrin in South Africa and Sustiva in the U.S.), an antiretroviral drug that prevents HIV from making copies of itself in the body. Instead of using efavirenz as it was intended – to keep the AIDS virus at bay – kids are crushing the pills and smoking the powder to get high, ABC News reports.
When taken as prescribed, efavirenz can cause side effects, including drowsiness and vivid, colorful dreams, but when smoked, it induces hallucinations and is highly addictive. "Once you've first started, there's no turning back," a 17-year-old addict told ABC News.

The undisturbed tropical forests of Africa—like the rainforest in Congo—remove 1.2 billion metric tons of carbon dioxide from the atmosphere every year. For the last few decades, that rate of removal has increased by 0.6 metric tons per hectare per year—simply because the trees are getting bigger and bigger in size, according to an analysis published in Nature today.
That's good news for those who are looking for ways to sequester carbon, which many say is necessary to curb global warming. "We are receiving a free subsidy from nature," said study co-author Simon Lewis of the University of Leeds, in a statement. He and his co-authors measured the girths of tropical trees in Africa—and hence CO2 absorption.
