These days a good weekend of partying (friday pm through sunday noon) runs me about $125-$200 for admission to an event or club, some good (6-10 for two nights) rolls or some molly, a few doses of some psychadelic(s), a bag of decent reefer, maybe some downers to kill time saturday afternoon and a few packs of smokes.
That's damn affordable compared to the cost of a weekend when I was a regular shard monkey. I'd buy a gram or so on friday and shoot/smoke all of it by saturday afternoon, buy another bag and keep repeating this process long past the end of the weekend and sometimes straight through till the next weekend. Mixing in cocaine, heroin, dilaudids, etc didn't make things cheap either. Those binges were fueled by selling/moving shards so I wasn't actually paying for all of my intake; but if I was I would go through about $150-$200 worth of shards a day...if I was speedballing or just getting twisted throwing other drugs into the mix it was an extra $50+ per day. During a rather hellish binge involving anything I could get into a needle I consumed over $1150 worth of substances between friday evening and sunday afternoon. It was the last weekend of a 8 day bender and I weighed 118 pounds at 6'2" when I checked into rehab the monday afterwards.
