No. Crack is a cocaine based drug that is often smoked or snorted.
It depends on the type of drug test. It also depends on how much you smoked before you stopped, and how much body fat you have.
It may be hash or residue from marijuana, scraped out and smoked again.
The first use of Marijuana was 4,000BC in Ancient China, used as hemp to make textiles. It was not smoked or consumed.
No.
