Cannabis which is also known as weed is a psychoactive drug (a drug that changes the brain functions) gotten from cannabis sativa plant used for recreational and medical purposes. Weed can be smoked, vaporized, brewed or eaten but most people smoke it. Tetrahydrocannabinol (THC) is the intoxicating chemical contained in cannabis.

According to the Potency Monitoring Project, the average THC content in some retail cannabis today is 30% as against 13% THC content in 2010. This increase in potency makes it more challenging to determine the long- and short-term effects of cannabis.

Consumption of cannabis produces a wide range of effects, and these effects vary depending on several factors, but all effects are temporary.  How the phytocannabinoids in cannabis interact with endocannabinoid system within the body can produce a wide range of short-term effects on the mind and or the body. These effects vary from one person to another, and it also depends on the physiology of the individual involved, the strain of the weed, THC content, how much is consumed and how it is consumed.
