I have to agree, once a week is not frequent, funny thing is that I have not smoked for the last month because is something that I can stop at free will. To me an addiction is something you can't willingly stop on your own, such as tobacco users who can smoke up to a pack a day. I have recently stopped just because I don't need it, just like I don't need wine - While several months ago, I was having wine every week, I now have wine maybe once every three months, but with Marijuana being so widely used and now being legalized in several states, I was just curious. I am sure everyone has their own perception, and I have agreed for myself that smoking marijuana would not be best for me after surgery, but I would welcome open minded perspectives to this subject on those that have used it and what was the experience.
