Marijuana addiction is simply an unmanageable desire to own and use the drug. With marijuana addiction the person is not able to stop using the drug even if he/she wishes. Marijuana has been around for centuries and the plant has been used to make rope, thread, clothes and even smoked for its euphoric effects and medicinal purposes. THC is primarily the psychoactive component of marijuana and the potency depends on the method of preparation. The drug often causes euphoria, a sense of relaxation, sexual arousal and easier socialization with other colleagues and the easy availability, cheap price and minimum legal penalties is greatly responsible for the increased usage of this drug in the past 2 decades all around the world.
