I think anyone who claims cannabis helps weight loss is probably experiencing something else. Medical marijuana is not prescribed as a primary medication for weight loss and is not FDA-approved for that purpose. One of the oldest medically-approved uses of cannabis is to achieve the opposite. To increase appetite so you can gain weight. Especially for people on chemo and other medical conditions that reduce appetite and cause weight loss.
For every person who claims cannabis helps them lose weight, there are literally millions who see the opposite effect, and there are many years of research and solid medical data to back that.
Another thing I read in this thread was it helps "burnout". One might think that would be absurd too but in reality it isn't and there is some medical data showing that it can help reduce burnout from chronic stress, anxiety, and insomnia. I had to look that up because I found it hard to believe. I mean, when you think of the term "burn-out" a big thing that comes to mind is a spaced-out stoner locked in their LaZboy recliner with zero energy and motivation. But you learn new stuff every day.
I think you will find that there will always be people who think cannabis can cure every ailment in the world but if it does benefit them, a lot of the time it has caused a certain change in lifestyle which in turn has been the real effector and a lot of times things other than cannabis could have achieved the same effect.
Hey, but if it works for you... I say go for it! Party on!
