A crack cocaine overdose can be very serious and can result in long-term damage to the body of the user, coma, or death.
The high you get on a single dose of cocaine depends upon how you take it. In general, the effects of an ingested dose of cocaine lasts about 20-30 minutes. Peak levels of cocaine in blood plasma also vary by mode of administration. When snorting cocaine, levels peak around 30 minutes. In comparison, oral administration of cocaine usually results in peak plasma concentrations at 1 hour.
