Cannabis: a self-medication drug for weight management? The never ending story.

In a society highly focused on physical appearance, people are increasingly using the so-called performance and image-enhancing drugs (PIEDs) or life-style drugs as an easy way to control weight. Preliminary data from online sources (e.g. websites, drug forums, e-newsletters) suggest an increased use of cannabis amongst the general population as a PIED due to its putative weight-loss properties. The use of cannabis and/or cannabis-related products to lose weight may represent a new substance-use trend that should be carefully monitored and adequately investigated, especially in light of the well-known adverse psychiatric and somatic effects of cannabis, its possible interaction with other medications/drugs and the unknown and potentially dangerous composition of synthetic cannabimimetics preparations.
