"Marijuana vs Tobacco: Consider the Facts"

"smoking marijuana poses several health risks, including:

* Impairment of thinking, problem-solving skills and memory
* Reduced balance and coordination
* Increased risk of heart attack
* Heightened risk of chronic cough and respiratory infections
* Potential for hallucinations and withdrawal symptoms

A number of studies have shown an association between chronic marijuana use and increased rates of anxiety, depression, suicidal ideation, and schizophrenia. It not clear whether marijuana use causes mental problems, exacerbates them, or is used in attempt to self-medicate symptoms already in existence. Chronic marijuana use, especially in a very young person, may also be a marker of risk for mental illnesses, including addiction, stemming from genetic or environmental vulnerabilities, such as early exposure to stress or violence.

Perhaps most alarming is the documented adverse effects marijuana has on health:

* The Heart. One study found that the risk of heart attack more than quadruples in the first hour after smoking marijuana. This might be from marijuana's effects on blood pressure and heart rate (it increases both) and reduced oxygen-carrying capacity of blood.
* The Lungs. Marijuana smokers can have many of the same respiratory problems as tobacco smokers, such as daily cough and phlegm production, more frequent acute chest illness, a heightened risk of lung infections, and a greater tendency toward obstructed airways. Numerous studies have shown marijuana smoke to contain carcinogens and to be an irritant to the lungs. In fact, marijuana smoke contains 50 to 70 percent more carcinogenic hydrocarbons than tobacco smoke. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increases the lungs' exposure to carcinogenic smoke.
* Head and Neck. Smoking marijuana has been linked with an increased risk of head and neck cancers. Several case reports have found an unexpectedly high number of marijuana users among persons with cancers of the head and neck region, including the mouth, tongue, throat, and larynx.

The bottom line: The risks of using marijuana far outweigh the benefits."
