Scientists at the Technical University of Dortmund have grown a type of tobacco containing 99.7% less nicotine. CRISPR was used to disable certain plant enzymes aiding in nicotine production, potentially creating a tobacco to help users quit smoking.

The research, published in the Plant Biotechnology Journal, states that the new variant has around 0.04 milligrams of nicotine per gram.

Though low-nicotine cigarettes are just as harmful as normal cigarettes thanks to other substances and carcinogens, studies have proven that smokers switching to less nicotine do not smoke more to compensate for the loss.

Currently the FDA is exploring policies to introduce new product standards with lower nicotine.
