A: Marijuana contains the chemical THC which is a mood and mind altering drug. THC occurs naturally in marijuana plants and when taken into the body causes a ‘high’ feeling in the brain. Marijuana is most commonly smoked, although it can be ingested in the form of various foods. It has not been scientifically proven that marijuana or THC is addictive, however if used over extended periods of time in a habitual manner, a person can develop a dependence on marijuana. Many people use the justification that, “marijuana is not physically addictive”, therefore they do not have a problem, however, marijuana can negatively affect a person’s life on a number of different levels. Marijuana decreases short-term memory capacity, creates confusion, paranoia, anxiety and restlessness. In addition marijuana can negatively impact a person’s motor skills as well as his/her ability to feel emotions. Marijuana is often used in combination with other drugs and treatment for marijuana abuse is available and readily utilized.
