The reason why this happens is because cigarette butts contain a filter, which comprises of cellulose acetate fibre - a type of bioplastic, toxic for soil patterns.

Even though seriously harmful for the environment, dropping butts is a socially acceptable norm, which people take very casually, believes the study's lead author, Dr Dannielle Green. 


Dr Green adds: 

Despite being a common sight littering streets and parks worldwide, our study is the first to show the impact of cigarette butts on plants. We found they had a detrimental effect on the germination success and shoot length of both grass and clover, and reduced the root weight of clover by over half.

Cigarette filters take years, if not decades, to naturally break down, reveals the study's co-author, Dr. Bas Roots. 


Surely something to ponder for this generation and its smoker population.
