What is the ratio of weed smokers to non-smokers?

It's difficult to provide a precise ratio of weed smokers to non-smokers, as it can vary depending on various factors such as demographics, geography, and cultural norms. However, according to a 2019 study conducted by the National Institute on Drug Abuse (NIDA), approximately 13.6 million Americans aged 12 or older had used marijuana in the past month, representing about 4.3% of the U.S. population. This suggests that there are approximately 23 non-smokers for every weed smoker in the United States. However, this ratio may vary significantly based on specific populations and regions.
