As someone who's used cannabis regularly for over a decade, I tried to start to explain in this body my experience but every sentence written ends with me deciding, "that's too circumstantial to my lifestyle-physiology to include."
I think at the end of the day, empirical research's purpose is to get us closer to being able to just make our own decisions surrounding mind-altering drugs. Beyond that, cannabis affects a great deal of systems in our body concurrent to the rest of our environment's effects. Use your autonomy to determine if it's a positive or a negative for you. Don't drive fucked up, please.
