Cons
Short-term Effects
Distorted perception (sights, sounds, time, touch), problems with memory and learning, lack of proper coordination, trouble with problem-solving, increased heart rate and reduced blood pressure are some of the short-term effects of marijuana.
Effects on the Brain
Marijuana contains an active ingredient, delta-9 tetrahydrocannabinol or THC that acts on the cannabinoid receptors of the nerve cells and influences the activities of the cells, like pleasure, memory, thought, concentration, sensory, time perception and coordinated movement. High doses of marijuana, when consumed through food, can cause hallucinations, delusions, impaired memory and disorientation.
Effects on the Heart
The heart beat increases rapidly and the blood pressure drops within minutes of smoking marijuana. A person’s heart beat can increase by 20 to 50 beats per minute. A marijuana smoker is three times more at a risk of heart attack.
Effects on the Lungs
Burning and stinging of the mouth and throat and heavy coughing are some effects that are caused by smoking marijuana, even infrequently. Marijuana causes respiratory problems in smokers, such as daily cough and phlegm production, more frequent acute chest illness, increased risk of lung infections and obstructed airways. Marijuana smokers are three times more likely to develop head and neck cancer, as compared to non-smokers.
Effects during Pregnancy
Studies have found that mothers who have used marijuana during pregnancy have given birth to children who are likely to exhibit problems with neurological developments. Prenatal marijuana exposure can cause altered responses to visual stimuli, increased tremulousness, problems with sustained attention and memory and poor problem-solving skills.
Other Health Effects
Researches indicate that the THC found in marijuana impairs the body’s immune system from fighting diseases that result in a wide variety of health problems. It increases the risk of developing bacterial infections and tumors as well.
