Hello. I had a few questions I was hoping I may be able to get some responses to. I smoke marijuana essentially every weekend, maybe sporadically during the week every once in a while. I've noticed that the day after I smoke, and usually several days after that, I feel "burnt out" and less intelligent. Is this normal, and are there any ways to prevent this? I usually only smoke one or two bowls, but i'm pretty light so it doesnt take much.
