like I guess for like 3 weeks now every saturday I've started drinking not much like a couple beers but also with weed. Uhm I've heard that weed and drinking are bad for muscle growth can someone tell me why. I'm not trying to debate it and stick up for either of them I just would rather keep my body healthy. When I say healthy I mean muscle wise but that doesn't mean i would be doing steroids. I'm kinda scattered uhm heres what I mean. Will drug or alchohol use reverse muscle growth.
