Even with a passion for crack, budgeting and saving a rainy day fund is always important! Better to start later on than never at all, you know?
I personally often save upwards drug purchases in little bits, instead of dropping $200 on something at once I'll put $50 away every check and buy it two months later, that kind of deal. It lets me really think through decisions and purchase large amounts for a long term stash, minimizing total purchases and also giving me good clearance to only need to test one batch for purity/reagent test/recrystallize, to get the cleanest product I can. Buying things like a half ounce of ketamine, 600 tabs worth of LSD in 5-10 mL of saline, a quarter ounce of 2C-B, a full pound of Panaeolus cyanescens mushrooms, huge hunks of ayahuasca vines, kilos of coca and ephedra teas, all of these things help me build a really nice long lasting stash of things that I enjoy. The only thing I go through too damn fast is acid, god it's easy for me to just do half a sheet's worth every 1-2 weeks, it can be a financial drain to always keep as much acid on hand as I'd truly like to.
Sorry for the rant, Bupropion's got me sped up.
