Marijuana originated from the Cannabis sativa plant. It also has some familiar names such as weed, cannabis, grass, pot, herb, Mary Jane, and bud; it comes from dried parts of the plant. It includes THC, a euphoric substance that alters your brain functioning, similar to other drugs. In the US, it’s the most often used illegal chemical. Usually, individuals inhale it in water pipes, frequently known as bongs, or in cigarette rolls called joints. Others smoke it as blunts, which are simply cigars with the tobacco removed and the marijuana added back in. The smell of weed smoke is powerful and unpleasant.
