I used MMJ for medical reasons. There are so many different strains out there and plenty that do not cause munchies. If you go with a strain with more CBD and not as much THC then it is more for pain managment, body buzz opposed to heady high and munchies. If it is something that you need or even chose to use; just research strains.
I don't think anyone anywhere including here can/should judge anyone else for the way they choose to live an everyday life occurance. Everyone here is here for the same reason, to lose weight and have support. Not to be judged on other things we do. All of us have our own opinions, if you don't think it is a good idea; simple state that. Don't go on to put each other down. Especially someone who had to go through surgery to lose weight; how can you judge others for what they need to do to get by. Too each his own!
I say if you can handle and get your hands on the right strain for you; go for it. If it doesn't work and you start eating because of it; yeah might want to let it go.
Good luck to everyone!
