Many individuals believe that smoking marijuana does not cause any harm. However, scientific studies have proven that smoking marijuana carries various inherent health risks which can affect addicted individuals, especially adolescents. Smoking marijuana can result in poor judgment and can even damage a person’s brain and keep it from functioning normally. For those individuals who use this drug repeatedly, it can result in poor performance in school or at work and can even lead to addiction.

After smoking marijuana, the drug’s chemicals flow through the body. Tetrahydrocannabinol also known as THC is the most potent chemical which marijuana contains. Once THC goes enters a person’s system, it normally reaches the brain within just a matter of seconds and then quickly begins to effect the brain.


What is THC?

Tetrahydrocannabinol or THC is an addictive chemical which can be found in marijuana. It is the chemical that is responsible for the psychological and physical effects when a person smokes the drug. Smoking marijuana can lead to feelings of euphoria, tranquility, decrease inhibitions, fragmented thoughts, inability to focus, weakened memory, sleepiness, and even feelings of paranoia. Cannabis abusers may also experience physical effects such as dry mouth, an increased appetite and heart rate as well as reddening of the eyes.

THC moves through the body very quickly. When the drug reaches the brain, it passed through the brain’s nerve cells. This active chemical copies the naturally occurring neurons in the brain know as Anandamide. Anandamide is the neuron which is responsible for learning and improving memory, reducing pain, and stimulating the person’s appetite. Though THC copies Anandamide, it does not necessarily mean that the chemical produces the same results as with the natural neuron which comes from the brain. THC prevents Anandamide from doing its job. As a result, marijuana abusers end up feeling euphoric, voracious, off-balance, resistant to pain, and unable to receive information properly.

Many health care professionals see marijuana as an addictive drug which can destroy people’s lives by causing them to become dependent on the substance. While it can be considered a cure for insomnia as well as for glaucoma when prescribed by a doctor, it should only be used as directed. It is scientifically proven that marijuana has some medical benefits, but getting addicted is a different story. As with all medications, people must be careful with their use.
