I just wanna know how long the coke high lasts, off lets say one decent sized line. By coke high i mean how long do u feel the full effects of the drug. To make a comparison, I would say the "high" for weed lasts on average45-60 minutes, in some cases definitely more but some people might say weed high lasts like 2-3 hours but they are including the comedown and after affects. I am just wondering how long you feel the full effects of coke for after doing an average dose. thanks.
