How long does smack stay in your system?

Answer 1

Heroin, commonly referred to as "smack," can be detected in the body for varying lengths of time depending on the method of testing. In general, it can be found in urine for about 1 to 3 days after use, while blood tests may detect it for up to 6 hours. Hair tests can reveal traces of heroin for up to 90 days. However, individual factors such as metabolism, frequency of use, and overall health can influence these detection windows.
