Yeah cocaine in our country is usually very weak. I considered myself lucky when i got cocaine that was 25%, most people that i have known just do bumps or one line and wait until it wears off to do more.
But i didn't feel much of a difference off one line (pretty big too) so i did a second (equivalent to 50% cocaine) slightly numb, pretty damn energetic tingles over body. And then i did a third line and that's when i felt the true effects of what high quality cocaine feels like. My mouth went totally numb, than my face, than my whole body, and instead of running around with energy i felt more tired and mellow but in a good way.
Most people claim that cocaine has them running around, talking a million miles per hour etc, but if you do good cocaine and have just a line or a few at once you will notice that cocaine is a more numbing mellowish high, weaker cocaine or lower dose means either its cut which a lot of the cocaine in our country is, or you didn't do enough (at once) in lower doses of cocaine it's more energizing.
I have done cocaine a few times but not a lot because of how impure it usually is, last week i bought some for 10 bucks and it had 3 good sized lines, it burned a bit (good coke does not burn your nose, if anything it numbs it) so i knew the coke was shitty but that's why i drank 5 beers beforehand since i never really experienced the cocaine/alcohol combination that is very euphoric. I finished all the lines at once and felt pretty talkative, slight body high, in other words the cocaine literally was like 5% but mixing it with alcohol made me notice a little bit more but also created a bit of a different feeling. Ugh sigh, cocaine is so cut in this country. Consider yourself lucky if you even get 20% these days
