I am doing some research into drugs and drug tests and wondered if anyone had a good list of the types of drugs and how long they stay in your system depending on the types of test e.g. urine, blood and hair tests.
I have found these websites useful.
In summary, for those who want to find out how long drugs stay in your system the answer is not simple. Many factors influence how long a drug remains detectable eg.
Amount and frequency of use
These websites will give you time ranges based on upper and lower boundaries. They also explain types of tests used and provide good drug information.
