How Does Marijuana Affect Blood Pressure?

CBD and THC are the two primary active ingredients in marijuana.

You may be familiar with the most prominent and well-known components of cannabis: THC. THC has many effects on the body, and is the compound responsible for getting you high when you consume cannabis. CBD, on the other hand, is less present in cannabis. CBD has its own effects on the body, and is becoming increasingly popular for medical uses.

Here we explore the history, effects, controversy and scientific knowledge behind CBD.

Cannabidiol (CBD) is one of over 100 naturally-occurring cannabinoids in the cannabis plant. After THC, it is the most prominent component of cannabis and is found most readily in hemp.

Unlike THC, CBD does not produce a “high” that cannabis use is known for. It is therefore generally used more for medicinal rather than recreational purposes.

History

Although cannabis use has been documented as far back as 2727 B.C.E.1, it wasn’t until the 1940s that chemist Roger Adams first isolated CBD from the cannabis plant2.
