Historically marijuana (medical termed as Cannabis) has been promoted as a medical drug used as general analgesic, treatment for psychoactive disorders and improvement of nausea or vomiting. However, abusive usage of this drug led to the limiting of the usage, production, planting and sales of the drug.
Marijuana is often smoked for its psychoactive effects such as mood elevations, relaxations, and it can change appetite. Drug users often acquire this drug for enjoyment but it comes along with some negative effects. These are the loss of motivation, reducing physical/voluntary movements, reddening of the eyes, extreme feelings of paranoia and anxiety which leads to depression, audio and visual hallucinations, disruptions in sleeping habits, dry mouth and increased heart rate.
It is said that people taking marijuana can haved changed personality and character because of its effect in the brain. The chemical in marijuana is active in the reward system part of the brain that responds to natural pleasures such as food, music or sex. With excessive usage, the response from that area is heightened, which eventually puts the person in the state of euphoria or hallucination, which can affect the attitude, personality and character of the user in the shor term. When the person becomes adicted or use becomes abuse, then the change to personality and character can become habitual and is shown in severe depression, a tendency to weeping, extreme drops in self-confidence and self-esteem, ominous forboding of having done harm, altered perception and cognitive function.
