A new study suggests that those who smoke marijuana daily have a lower BMI than those who don't.
The study found a direct correlation between marijuana use and a lower BMI, according to Live Science.
The researchers looked at more than 13,000 adults aged 18 to 26, comparing participants’ use of marijuana and changes to their BMI over a period of six years.
The men who smoked marijuana had a BMI which was 2.7% lower than non-smoking men, and for smoking women it was 3.1% lower than for non-smoking women.
The research was published in The Journal of Mental Health Policy and Economics, and contradicts some previous studies that had mixed results.
However, the researchers are not advocating the substance as a weight loss tool as it can lead to health effects on the brain and heart.
Researchers revealed they are not certain what causes the link, but it could be that those who smoke marijuana break down blood sugars more easily.
