I'm 40 years old and hit a weed vape for pre-workout. I occasionally take 5mg edibles at night for sleep and creativity. I haven't had any alcohol in 5 years. I am married with kids and I'm probably the most fit that I've ever been. When I used to drink, I could literally feel years of my life slipping away and the amount of money I was spending on alcohol was far more than I should have been comfortable spending because I was an islay scotch fag.

My consensus: both are probably bad in excess, but alcohol far more so.
