I’ve recently used Cocaine and found it to only give me a numbing sensation in the nose (becomes a little runny as expected) and throat (after it settles in) there isn’t a strong stimulate feeling whatsoever. I’ve had more of a buzz from large doses of coffee even, is this normal or would higher purity coke cause a lack of speediness?
I was a regular user of Ritalin as a child (about 5 years or so) if that matters.
There is no cross tolerance between caffeine and cocaine, so the fact of large doses of coffee does not affect effects of cocaine. Previous use of methylphenidate (years ago) does not cause tolerance, neither.
“Numbing sensations” are not indicative of cocaine purity. In fact other topic anaesthetics (lidocaine, tetracaine, benzocaine…) are among the usual adulterants of cocaine and they are used because of this sensations. Probably a low quality of cocaine is the cause of these feelings without stimulation.
