Toxicological tests for detecting compounds present in cannabis, commonly known as marijuana, can be challenging, but understanding the different types of tests and their peculiarities is essential before undergoing a test.
Detecting THC, a psychoactive compound of the plant and often seen as a “villain” by many, may require a deep understanding of the different available methods. Get to know the four main types of tests and their distinct characteristics.
1. Urine Test:

2. Blood Test:
