A vast array of studies have brought about the same conclusion when it comes to waistlines – they’re smaller if you’re a pot user. Why? Well, some say it’s all about favouring calorie-free pot over other vices, while others cite the natural metabolism-boosting properties of cannabis as the main contributor. Whatever it is, we know for sure that cannabis is a good tool for staying slim. And as a lower BMI means less chance of heart attacks, stroke, cancer and so on, this is a good thing.
