Cannabis (also known as marijuana) is the most frequently used illicit psychoactive substance in the world. Though it was long considered to be a "soft" drug, studies have proven the harmful psychiatric and addictive effects associated with its use. A number of elements are responsible for the increased complications of cannabis use, including the increase in the potency of cannabis and an evolution in the ratio between the two primary components, Δ9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (toward a higher proportion of Δ9-THC), Synthetic cannabinoid (SC) use has rapidly progressed over the last few years, primarily among frequent cannabis users, because SCs provide similar psychoactive effects to cannabis. However, their composition and pharmacological properties make them dangerous substances. Cannabis does have therapeutic properties for certain indications. These therapeutic applications pertain only to certain cannabinoids and their synthetic derivatives.

Marijuana or Cannabis to some people has been debated for years. Many conversations have taken place because some states have legalized the use of marijuana for recreational purposes. Some sectors are pushing for marijuana to be legalized for medical purposes.
