Because depressants will make you suck at video games. You gotta get into stimulants to combo with gaming. On the plus side, if you get into meth or crack, you’ll have the energy to hold down a part time job and full time gaming addiction for a few months before you start to come apart! Then you’ll have a few more months of just cracked out gaming after you get fired before you’re evicted. If you’re lucky and steal some wifi, you could eek out a whole year of 40+ hour gaming weeks of erratic, aggressive high level play. You’ll set random records. You’ll birth new slurs to yell at children. You’re not gonna accomplish any of that on heroin. You’re really gonna let people down on heroin.
