Can drugs be detected in yiur hair after 90 days?

Yes, drugs can be detected in hair for an extended period, often up to 90 days or more, depending on factors such as hair growth rate and the type of drug used. Hair typically grows about half an inch per month, so a standard hair drug test can analyze the length of hair for substances consumed over the past three months. However, detection may vary based on the drug's properties and individual metabolism.
