How could you use your money if you didn't smoke?

The pack of cigarettes costs about 30 roubles. On average, a teenager needs to use one pack per day.
These are things one can spend to in a month period, either:
- nine books
- 30 audio cassettes
- 15 kilos of sweets
- to go to the cinema 10 times
- 15 hours in the swimming pool
- half money needed to buy the cheapest mobile phone
