However, psychomotor impairment can remain after the initial high effects have worn off.n urine, THC is noticeable up to 3 days after the last dose of marijuana. However, chronic use can be detected weeks or months after last use. And as with any other drug, marijuana is noticeable for 90 days minimum in a single human hair.
A crack high lasts about as long as a cocaine high does (since crack is just a diluted, easier-to-smoke form of cocaine). Which is not very long. The effects of one line of cocaine, or one hit of crack, last about 20 to 30 minutes, and then you have to take another line, or another hit, to keep the high going.
