At 72, my experience is somewhat similar. Started using it frequently around 15. Quit during military service 20-24; drank alcohol like a fish when my ship was in port. After completing service I studied hard at university staying mostly sober in all regards there except for Friday nights, which were party nights for blowing off steam (mostly alcohol but some cannabis got sprinkled in). Graduated Summa Cum Laude in mechanical engineering. Restarted briefly after graduation but stopped everything for 25 years after my first child was born.

I used daily as a pain killer for about about 6 years when my knees went bone-on-bone. A puff or two every few hours. I went through 4 major surgeries after waiting a year and a half while elective surgeries were shut down due to the Covid game (unfortunately one knee got infected which lead to two additional surgeries on that knee.) It's the best pain killer of all time. Currently, I sometime take a puff or two before bed but it's no big deal if I do or don't. But I've stopped all alcohol and most sugar.

Never jabbed, started taking Ivermectin horse paste monthly (or more) Dec 2020. Haven't had so much a cold since then. Now my knees have been replaced I'm one of the healthiest people my age. Cannabis has been good medicine, and not been addictive for me.
