I have always always thought of cannabis as a tool. It depends how you use it, how often, and your tolerance to it. If all someone does is smoke and veg out on the couch playing video games and other mindless tasks I think it can have some negative effect on your well being, motivation, and social life. I prefer to read, research, and educate myself after a few puffs. I have also had some of the most focused, intense workouts in my life after smoking the refer.

I think I have some form of undiagnosed ADHD and my brain runs 100 miles a minute all day long and into the night. I find it just helps slow things down so I can focus on the task at hand or fall asleep when I need to. Just gotta have rules for yourself, use it responsibly, and don't let it interfere with work or relationships.
