I had a really weird few days . Yesterday , I ate lunch , got some errands done ( including mailing something awesome to Martin ; I hope it gets there unsmooshed ) , and went to a cafe downtown to do some journalism reading . I ordered one of those flavored blended espresso drinks . I do n't know what was in that drink ( probably just caffeine and sugar , but still ) , but it hit me hard . I was SO INCREDIBLY EXCITED about everything I was reading in my journalism textbook , I had trouble focusing because I wanted to get up and dance around going " Squeeeeeeeeeeee ! "

Question: What about the drink led the speaker to have such a strong reaction ?
Answer: It had been laced with amphetamines , which is why they had this reactionThey had a low caffeine tolerance and were not accounting for this when they consumed the drinkThey had accidentally put 5x the normal amount of caffeine into this particular beverageOne of the workers had slipped cocaine into the beverage , leading to this this result
