What would yall say is the ‘cheapest’ drug habit

I dont do much, but i smoke a ounce in 4-7 days, so im spending about 4-500 a day on weed. I know cocaine is a ‘rich mans high’ and shrooms can literally be made for almost no money if you have the right stuff. And i also know, fentanyl is super super cheap. What are yalls current drug habits aswell? Edit: not a day, i spend 4-500 every like two weeks, idk wtf i was on when i wrote this, i get qps.
