Drug Recognition Expert Practice Exam

Marijuana is most commonly derived from the Cannabis Sativa plant. This plant is characterized by its tall, thin stature and narrow leaves, and it typically produces a higher concentration of THC (tetrahydrocannabinol), the psychoactive compound that causes the euphoric effect associated with marijuana use. Cannabis Sativa is known for its energizing and uplifting effects, which is why it is a popular choice among users.

While Cannabis Indica is another species that can also produce marijuana, it generally has a different effect profile, often associated with more sedative qualities. Hemp, which is derived from Cannabis Sativa, is cultivated primarily for industrial uses and contains very low levels of THC, making it unsuitable for recreational use. The opium poppy, on the other hand, is unrelated to marijuana as it produces opiates such as morphine and codeine.

Understanding the differences between these plants is crucial for drug recognition experts, especially when identifying marijuana based on its characteristics and effects.
