There are only negatives with chronic cannabis use.
Not true for me. I indulged a lot, almost every day from 16 until 34. I was a jock (football and track), played sax in HS band and was a stoner, while making straight A's in school and college. Was president of the science club and made all conference in football.
I dropped out of college (big waste of time) after 1.5 years to start making money as a software programmer / designer (self taught) while playing in various mostly heavy metal bands (bass, guitar, sax, keyboards, violin, some vocals, all self taught). I comfortably retired at 62 and now I use edibles whenever I'm in the mood. I also like good Scotch and Brandy.
There were no negative effects for me other than what I mentioned in the previous post about making even bad music sound good. Stopping was a negative effect for me because my creativity suffered.
I had to stop when I was 34 because I became subject to random drug tests since I was working with/creating software that had very high security requirements. Fortunately that BS ended when I retired.
Edited to add: I had a full time job from 15 until 62. First job was a dishwasher at a restaurant making $1.25 an hour. Cannabis never affected my drive to succeed. I believe it actually helped me. I believe it enhances who you already are and relaxes mental blocks that slow down creativity.
