This is among the first studies to report biomarker metal levels among marijuana users and most likely the largest study to date, that links self-reported marijuana use to internal measures of metal exposure, rather than just looking at metal levels in the cannabis plant. The results are important because marijuana is the third most used drug in the world.

A new study suggests that these devices may help people decrease their dependence on combustible cigarettes -- which contain an array of harmful chemicals called toxicants -- without increasing their overall nicotine dependence.

Treatments such as deep brain stimulation hold promise for helping people overcome addiction, but many questions remain about what brain areas should be targeted. Researchers are gaining new insights from patients who are no longer addicted to nicotine after experiencing a brain lesion, such as a stroke. Using a new technique known as lesion network mapping, researchers have mapped addiction remission to entire brain circuits rather than specific brain regions, pointing to new targets for treatment.

While scientists are still working to understand what spurs cancer in so-called 'never-smokers,' a study suggests that 78% to 92% of lung cancers in patients who have never smoked can be treated with precision drugs already approved by the Food and Drug Administration to target specific mutations in a patient's tumor.

Their findings point to the opioid system, the brain functions responsible for addiction and appetite regulation, as a possible cause for smoker preference of energy-dense, high-calorie food during nicotine withdrawal.

This study describes three molecular subtypes of lung cancer in people who have never smoked. These insights will help unlock the mystery of how lung cancer arises in people who have no history of smoking and may guide the development of more precise clinical treatments.
