Hi Nathan!
Thank you for sharing your story. From what I've seen so far is that people who smoke on a daily basis do not see any of the adverse effects. They've come to the stage where not smoking causes side effects, such as inability to fall asleep and anxiety.
Yes, I agree with you that "moderate" means an entirely different thing for each person. One cannot argue that cannabis has its benefits, and they may be a lot, however, research is still lacking on the drug's long-term effects on chronic users. It would be beneficial if people knew what years of smoking would do (or not do) to their brains and lungs.
