Look you don’t even need to try that hard. Just invent energy vapes, work a brand deal with Red Bull, get that evil flavor in them and cram it full of caffeine. Some of the two nastiest addictions still legally distributable, they take separate fast tracks to the brain, and layer the buzz, they cover each others immediate draw backs, and ruin other competitors, as just a cigarette or just an energy drink will fail to fire both commons at once, causing using either to condition a caffeine vape.

It will damn humanity to exploding hearts for the weakest willed, and life time devotion from everyone else. Just pure evil.
