How did the other Wes Moore's first experience with alcohol impact his decision to sell drugs?

Wes's first experience with alcohol and drugs makes him feel exhilarated and shows him exactly what addiction is; he realizes that he can make money from feeding other people's addictions.
Wes and Woody meet up to skip school; Wes stole marijuana from his mother to share. The boys and some friends pick up Mad Dog 20/20 and rolling papers, then go sit under a bridge to have both. After awhile, they go to get Chinese food.
Wes is clearly affected. He's very slow on the bike ride and thinks a trash can is a pretty girl.
That night, he lays in bed as he recovers from the day. He feels excited about having been under the influence and recovered from it. He realizes that the feeling makes him forget everything else, and that it's an addictive feeling. That feeling, Wes thinks, can help him make money by selling the drugs that people want and need.
