Environmental experts have called for strict implementation of the ban on public smoking as callously discarded cigarette stubs are a health and environmental challenge.
"The non-biodegradable nature of cigarette butts, a hazardous solid waste, make it a challenging area to address. The butts also contain dangerous chemicals such as cadmium, arsenic and lead," environmentalist M.K. Prasad said in a statement.
"Stricter implementation of laws on public smoking will not only improve public health but also restrict environmental damage," said Prasad.
"Developed countries have woken up to this fact and have undertaken steps to identify the enormity of the problem. According to one estimate, the overall littering rate for cigarette butts in America is 65 percent," said Prasad.
A paper published in the International Journal of Environmental Research and Public Health cites that an estimated 1.69 billion pounds of butts are littered worldwide a year.
