A.

Cocaine provides its high by quickly achieving high levels in the bloodstream during use. Smoking or injecting cocaine results in peak blood levels and effects on the body within a few minutes. After snorting cocaine, blood levels and effects of the drug reach their peak after about fifteen15 minutes. During this time, cocaine produces an intense high (and an increased risk of  damaging effects on the heart and blood vessels, and sometimes other organ systems).

Blood tests can detect cocaine itself for about 12 hours after use. Urine tests check for metabolic byproducts of cocaine, and in infrequent users a urine test is positive for up to two to three days after cocaine use. However, in those who use cocaine regularly, a urine test may be positive for two weeks after the last use. Hair samples can detect cocaine for several months after using.
