Word....and I found coke quality has a lot to do with it as well, though there's people that think good coke is like the coke they are used to and do movie sized lines....I've had 1.25 grams since friday, and I'm still doing some and have about 0,5 left...I used to smoke crack and IV the shit, but nowadays I just do it if it's quality peruvian fish scale, with where I live I pay one figure in dollars for a 0,7-0,8gr 'gram' but that lasts me for a couple days, and I can eat and sleep...the reason I noted the most is people overdoing the size of lines, with quality shit I just need a bump, max a 75mg line.
It doesn't hurt nor have such a disgusting anesthesia drip, though it numbs your face and clenches your jaw a bit when you've been overdoing it.
My recommendation: if it puts a dent in your pocket like say Acid down here does in mine or more like if there was Heroin the prices I paid for when I was a junkie like a decade ago down here but you can't compare the clean spiritual discovery feeling of Acid with even the smallest rail of colombian cociane crystals....unless you're doing opioids on top, and even then the impulsiveness of coke puts it in another ballpark completely but now I'm opioid free, have been for over a month, so I take my coke with lope when I start and benzos...loads of them, especially Midazolam (orally, I get the Dormicum tabs here, I loved IVing the shit ages ago, but haven't Ivd in almost 7years) Alprazolam and Zolpidem (a z-drug but it works wonders)....if you can't afford it (I mean everyone can afford a 20bag, but I mean can't afford it in the long run.....and you may be one of the unlucky ones that gets hooked, it happened to me with opies, I thought I was just dabbling, filling a list, being like my heroes...and damn it costed me so much at all levels, I mean my closest friend dying, my family never trusting me 100% again, losing jobs and opportunities and also the financial dent...so with such impulsive drugs it's good to look at your economy....damn I buy Ounces of bud every 2weeks or so, but if I could I'd be buying each week....I just smoke skinnier J's/vape less.
Same concept is extremely difficult to apply with coke, I personally used to know and get fucking blasted with some people that were/are coke heads and have 6 figure paying jobs or are in government positions, media, you name it, I also knew people with extremely big self control like my Sister (that probably from having me as an example) just dabbled in her teens year, tried everything a few times and then quit everything for good without a problem, she would just use once in a blue moon, but wouldn't turn down some H,Coke,Oxys,Crack You name it....she never had an addictive personality, whilst I did, nowadays if you saw her you'd never guess all the drugs she did in her young years we share the same genetic pool, so just to show how addiction is such an unpredictable bitch
Funny thing about coke is it put less of a dent in my pocket than good strains of bud here, that are just for the hipsters (due to prohibitive prices) and it's the same than buying in a coffee shop or in christiania in denmark in Euros for a G, an Oz has a good int'l price, and the quality of the growers I know is amazing...my advice would be don't buy it, have someone else buy it, you can fork in half of the money and do a test bump and go from there...and better have benzos beforehand, well I need benzos for everything, but still.
Good Luck, then the hygiene part is really important, never use a bill or share a toot, I have OCD soI take it way farther repacking my shit in ethanol washed brown glass dram vials, washing my hands (or using hand wipes or purell) before every bump/line, and washing the razor blade/card in ethanol (and wipe it dry of course), using saline and benzedrex/vicks, and blowing my nose a lot....hope my advice helped you in some way
