Question

Quizplus · Accepted Answer

Studies have shown that marijuana smoke contains higher levels of cancer-causing chemicals than tobacco smoke, potentially increasing the risk of lung cancer and other respiratory illnesses in heavy users. However, this does not necessarily mean that smoking marijuana is more harmful than smoking tobacco overall, as tobacco is often consumed in larger quantities and is also linked to a range of health problems beyond cancer.
