Metals that can cause cancer are present in higher levels in medwakh and shisha products than in cigarettes, a new UAE study found. Scientists in Sharjah and Abu Dhabi found that in comparisons to cigarettes, both medwakh and shisha tobacco contain more nickel, chromium, copper and zinc. The research follows a study earlier this year reporting much higher levels of nicotine and tar in medwakh than in cigarettes.
