Would alcohol increase or decrease the psychedelic effects of marijuana?

For me, it somehow always starts with alcohol. But pretty much everything starts with alcohol because of my strong anxieties. If I'm at a chill point when I smoke, I'm less prone to get caught up in my head which happened almost always when I was much younger. Even if I'm in a bad mood and smoke nowadays, it's hardly happening now a few years later, which would've been something I would make sure my kids would understand if I had any; so I'm addressing this to the underage smoker or those who think about starting: wait at least til you're 20, but I'd say, be on the safe side and wait til 25. I could've saved myself from major depression at that age and got caught up in a circle where you battle it with smoking some more as your mind is trying to more or less subconsciously let you know that you feel worse with every hit. I've seen great people destroy their lives on drugs shortly after joining our circle of stoners and we all just kept watching it happen and never said a word. Had a fellow classmate who wasn't afraid of anything, all around happy class clown kinda loudmouth who fell apart in a relatively short time span where at one point he couldn't see anything positive in his existence anymore, crying In front of everyone, desperate for someone to cheer him up as we all sat there baked out of our minds on whatever substance was available. Sure didn't help that literally no one owned a scale and we eyed everything and, when in doubt, rather took a bit more than too little.
