no. i mean all substances, and i dont mean in the sense that someone who's a drunk asshole is probably a sober asshole too since alcohol tends to amplify people's subconscious personalities. i mean habitual abuse of any substance over time, which becomes a thing at a point much earlier than people are willing to admit. alcohol gets dressed up in that socially-acceptable, "its 5 oclock somewhere," time-to-pound-a-six-pack-on-a-weeknight getup which suddenly makes it okay. its even worse with alcohol since it has that implicit harmlessness attached to it through its function as a social lubricant, and even through the fact that its legal and sold in stores.
on the whole personality amplification thing, i don't entirely buy it. i mean, sure, it amplifies people's personalities, but a repressed asshole who turns into a raging prick when he's drunk is still a raging prick when he's drunk, repressed assholishness be damned. if they're sober, theyre still just sober and not taking it out on people and hence not being an asshole (or as big of one as they would be when drunk). if getting drunk is what tips that person over into actually externalizing their asshole-ness, then getting drunk is still a problem. kind of like how someone lazy as fuck with no motivation can be made worse by getting stoned all the time; yeah, they were lazy as fuck in the first place but being stoned all the time isn't doing them any favours.
substance abuse isn't doing one of the ***super bad**** drugs like coke; you can do a couple lines at a party once and not be a cokehead asshole or roll hard once at a music festival and not be an e-tard, much like having a beer doesn't make you a drunk asshole (although you would probably have shittier friends). im not exactly sure where i'm going with this, just being a grumpy old bastard i suppose. it think the issue is that substance abuse becomes a thing at a point much earlier than what people are willing to admit + i've never met anyone whose life was improved by it = few years down the road people are fat and depressed and realize that hey, all that time i was having casual drinks after work and drinking a six because i can i didnt realize i was building up a psychological and physical dependency that made my life more shitty. not being judgemental, my life was pretty negatively affected by substances in general and i hate to see other people close to me (not just you phaggots) buy into it without knowing.
