I agree. I cannot understand why anyone needs drugs in a world that contains Haydn's Trumpet Concerto in E-Flat Major. I can get high just sitting and listening to it. Surely there are other things - music, art, books, movies - that would affect other people in the same way that music affects me. To me, drugs look like a quick way to get something that's better anyway if you earn it.
Classical music is definitely an acquired taste but if you choose a well-known piece and give it time with repeated listenings, it will grow on you and you will quickly explore other pieces.
For me, it was Beethoven's Ninth Symphony that brought me into classical music. I listened to that CD over and over again in the car and then it just hit me like a ton of bricks one rainy morning. Within a month, I had a car full of classical CDs. This was back in the early 1990s.
