I'd spend ...
80 bucks on a 10-strip of LSD
100 bucks on a half ounce of mushrooms
150 bucks on a gram of molly
110 bucks on a quarter of whatever heady strain is around (hopefully Mr Nice Guy or Sour Diesel)
30 bucks on a case of good beer (probably Newcastle)
25 bucks on a few packs of Djarum Specials
... and then I'd spend the last 5 bucks on rolling papers.
If this was all just for me, the weed and the beer would each last for a week and a half, the cloves would last for a month, the acid would last for 2 months, the molly would last for 3-4 months, and the mushrooms would last for a year.
