An estimated 30,000 people in Taiwan are believed to use ketamine, and long-term use of the drug can damage the kidneys, bladder and the brain’s cognitive functions, a physician said yesterday.
Stephen Yang (楊緒棣), surgeon-in-chief at Buddhist Tzu Chi General Hospital’s Taipei Branch, said one of his patients — a man surnamed Chen in his early 30s — began taking ketamine several years ago to reduce work-related stress, but continued use resulted in serious bladder damage.
After a year of use, Chen found himself having to urinate as many as 43 times a day, while his urine became sticky and thick with traces of blood, while his bladder shrank and became fibrotic, Yang said.
Chen underwent three surgeries over the past few years, but he was not able to quit the drug, and now his kidneys and bladder are so seriously damaged that he needs to undergo dialysis three times a week and use a bladder catheter every day.
Yang said 387 people are being treated for ketamine addiction in 12 randomly sampled hospitals nationwide, indicating that about 30,000 people are engaged in ketamine abuse based on Food and Drug Administration data last year on the rate of ketamine abuse among people aged between 12 and 64.
The data shows the rate of ketamine abuse in recent years is between 0.27 percent and 0.54 percent, while drug abuse reports from hospitals showed that ketamine is the most popular illegal drug among people under 19 years old.
“About 3,000 people with ketamine addiction suffer from serious bladder damage, with about 50 of them undergoing bladder- removal surgery,” Yang said.
A magnitude 6.4 earthquake struck off the coast of Hualien County in eastern Taiwan at 7pm yesterday, the Central Weather Administration (CWA) said. The epicenter of the temblor was at sea, about 69.9km south of Hualien County Hall, at a depth of 30.9km, it said. There were no immediate reports of damage resulting from the quake. The earthquake’s intensity, which gauges the actual effect of a temblor, was highest in Taitung County’s Changbin Township (長濱), where it measured 5 on Taiwan’s seven-tier intensity scale. The quake also measured an intensity of 4 in Hualien, Nantou, Chiayi, Yunlin, Changhua and Miaoli counties, as well as
Taiwan is to have nine extended holidays next year, led by a nine-day Lunar New Year break, the Cabinet announced yesterday. The nine-day Lunar New Year holiday next year matches the length of this year’s holiday, which featured six extended holidays. The increase in extended holidays is due to the Act on the Implementation of Commemorative and Festival Holidays (紀念日及節日實施條例), which was passed early last month with support from the opposition Chinese Nationalist Party (KMT) and Taiwan People’s Party. Under the new act, the day before Lunar New Year’s Eve is also a national holiday, and Labor Day would no longer be limited
COMMITMENTS: The company had a relatively low renewable ratio at 56 percent and did not have any goal to achieve 100 percent renewable energy, the report said Pegatron Corp ranked the lowest among five major final assembly suppliers in progressing toward Apple Inc’s commitment to be 100 percent carbon neutral by 2030, a Greenpeace East Asia report said yesterday. While Apple has set the goal of using 100 percent renewable energy across its entire business, supply chain and product lifecycle by 2030, carbon emissions from electronics manufacturing are rising globally due to increased energy consumption, it said. Given that carbon emissions from its supply chain accounted for more than half of its total emissions last year, Greenpeace East Asia evaluated the green transition performance of Apple’s five largest final
The first tropical storm of the year in the western North Pacific, Wutip (蝴蝶), has formed over the South China Sea and is expected to move toward Hainan Island off southern China, the Central Weather Administration (CWA) said today. The agency said a tropical depression over waters near the Paracel and Zhongsha islands strengthened into a tropical storm this morning. The storm had maximum sustained winds near its center of 64.8kph, with peak gusts reaching 90kph, it said. Winds at Beaufort scale level 7 — ranging from 50kph to 61.5kph — extended up to 80km from the center, it added. Forecaster Kuan Hsin-ping
