I know it's an old thread but I'd like to share some information about coke that I find important because there are worlds apart between real, pure coke and street garbage. I travelled with my sister to bolivia in 2014 and we visited the bar "Route 36" where they literally serve you whiskey and a gram of cocaine on a silver tablet for a couple bucks only. We experienced for the first time how REAL cocaine actually feels like. The "coke" you get in europe and the US is full of RCs that make you all antsy, jittery, paranoid and the crash is horrible. It makes you feel wired like speed does. It turns coke into a drug that doesn't feel like coke at all. Not so with the cocaine we tried in Route 36. Pure cocaine does NOT feel like a hard drug. The come-up of pure cocaine is smooth. You don't feel like your heart might break out of your chest, no paranoia, your ego gets a nice boost (not in the obnoxious egomaniacal "fuck y'all I'm the best anyway" sense, but more in the sense of "I'm actually a person with great strengths and only marginal weaknesses. I shouldn't be so hard on myself and be more proud of my accomplishments and who I am. I feel confident in my own skin."). You're incredibly clear headed and have creative thoughts. You like to socialize and talk, but it doesn't degenerate into verbal diarrhea that is so prominent with amphetamines. You can have intellectually stimulating and philosophical conversations that actually make sense. You don't become aggressive. Good coke doesn't numb half your face, only the parts it comes into contact with and even then it takes a while for the anesthesia to take effect. There is NO crash! Coke just gradually fades away after 30 - 45 mins and it feels like you are slowly descending on a cloud back to the ground. The fiendishness of pure coke is very subtle. You can take a line and when the high is over, you can just leave it at that and do another bump a couple hours later if you want and it feels like the first line again. You don't obsessively think about doing lines every 15 mins. The high gradually builds up and you're just satisfied with the effect. You only get paranoid on pure coke when you binged for days and didn't sleep. In that case it's the massive sleep deprivation that triggers psychosis-like symptoms and not the coke itself. With street coke you can get paranoid either way.
To put it more bluntly: real coke doesn't really feel like a drug. It feels like you've just been raised to the position of a managing director by the chairman of a multinational corporation due to your outstanding talent. THAT is how true cocaine makes you feel.
However there is a shadow side to cocaine, but that usually comes with long-term use: it stimulates your reptilian brain (the part that makes you think "what's in it for me") and can therefore make you incredibly cold-hearted and egotistical and these effects can CHRONIFY when you use cocaine for long enough and have a predisposition to exhibit such character traits. It can destroy relationships, so you need to be always vigilant when using this drug. It makes you much more impulsive. On top of that you can end up completely overestimating your own abilities. The movie Scarface, while completely over the top unrealistic, shows how cocaine users can pretty much end up in bad situations just because they overestimated their own abilities and did stupid shit to prove something that is beyond what they actually are/can/have. Just use this one rule when you're really going hard with cocaine: become and stay as self-aware as possible. It's very easy to get swept away by a drug that is powerful but subtle at the same time.
If I could describe the feeling of good coke with a song, it would be this:
And this is street coke, a degenerated, perverted version of the above song:
So if you really wanna enjoy cocaine, either go to bolivia, columbia, peru, or buy mate de coca teabags and synthesize your own coke. Everything else is a waste of money...
