Dangers of Marijuana

Dear Editor: Marijuana possessed in public and smoked in public for recreation is neither safe for driving nor for second-hand smoke exposure for non-users. Further, cannabis is not a safe drug for general private recreational use, in view of the body of toxicological effects.

Marijuana impairs a person’s ability to drive an automobile safely similarly with alcohol. This is because large numbers of cannabinoid receptors are in the basal ganglia and cerebellum, which function in motor control, and are also localized in the frontal cortex where binding of delta-9-tetrahydrocannabinol (THC), the major ingredient, distorts the sense of time. Plus, nearly 50 percent of regular marijuana users drink while using marijuana, which causes an additive deterioration in driving ability.

In terms of pulmonary effects, the toxic chemical components of both marijuana and tobacco smoke are similar, with ammonia, benzene, toluene, and naphthalene levels in marijuana exceeding those in tobacco smoke.

Research has shown evidence of bronchial irritation, inflammation and narrowing, reduced macrophage and ciliary cleansing mechanisms, and emphysema.

Further, as with alcohol, marijuana is associated with immunosuppression via cannabinoid receptors on spleen cells and lymphocytes, rendering persons susceptible to infectious diseases and cancer. The whole problem of the deleterious effects of second-hand smoke is thus widened with public marijuana smoking.

The argument to decriminalize marijuana, and basically legalize pot smoking de facto, if not de jure, on the grounds of its commonality with alcohol and tobacco, is absolutely irrational in view of the damning evidence of the latter products upon users and non-users in one way or another, from impaired health to social costs to the family and economy.

If anything, the most logical conclusion is to ban alcohol, tobacco, and marijuana, not to legalize toxins. As for medicinal uses of marijuana, other drugs are available for the therapeutic use in these symptoms and conditions.

The bottom line, as Comptroller Scott Stringer stated, is tax revenue from a legal marijuana industry. What has Stringer been smoking to impair his cognitive functioning?

One thought on “Dangers of Marijuana

  1. To Mr. Manago, who dedicated one sentence of this article to medical marijuana: You state that there are other drugs available for therapeutic use. You’re right. There are. They’re called opioids. (Medical Cannabis can be used for more than just pain, just for the record.) Opioid overdose is a very serious problem in this country. There were over 63,000 drug overdose deaths in the US last year and it’s expected to continue to rise. MC has the potential to get patients off of opioids. MC is a far less dangerous drug. I can’t understand why it is so stigmatized. There are many ways of administering it, not just by smoking it. It can be taken by mouth, through the skin, or by the inhalation of a mist. All medications come with risks and have side effects. The doctor and patient have to carefully weigh the benefits and risks of every drug being prescribed and then make an educated decision about it. MC should be one of the options for the simple fact that it is very effective in treating multiple medical problems and it is far less dangerous than codeine, Vicodin, Oxycontin, and other opioids.
