Seeing through the smoke: effects of pot

MARIJUANA: BOTH SIDES OF THE SPECTRUM

Benefits of using marijuana: – pain relief – stimulation of appetite – nausea control – relaxation – reduced eye pressure – euphoria – increased humor – heightened senses

Detriments of using marijuana: – short-term memory loss – impairment of motor skills, coordination and reflexes – difficulty with concentration and sensory and time perception – bloodshot eyes – dryness of mouth – increased body temperature – increased heart rate – associated with increased anxiety and depression

For Matthew, music just sounds better when he’s high.

“When I’m listening to music, and when I’m playing music, I can really focus,” he said. “I become more involved in the experience.”

Matthew started smoking when he came to college and now smokes about three times per week, enjoying a high that relaxes him and enhances his concentration. As for how it all works, the technical aspects are unclear.

“I think I don’t smoke enough to have any lasting effects. I don’t know, I hope not,” said the third-year mechanical engineering student, who asked that his last name not be used to protect his identity.

The research tells a similar story: Marijuana, the most commonly used illegal drug in the United States, makes you feel good. The research on long-term effects, however, still remains hazy.
“A big problem with the literature (on marijuana) is that some people want to find things, some people don’t want to find things,” said Sander Greenland, a professor of epidemiology and statistics at UCLA.

The short-term physical effects are clear: Within two to three minutes, users experience increased heart rate, increased body temperature, dry mouth, reddening of the eyes, muscle relaxation and reduced eye pressure, according to the National Institute on Drug Abuse. Motor skills, coordination, reflexes and attention may also be affected.

The psychological effect, known as a “high,” varies depending on the person and can include euphoria, relaxation, increased humor, heightened senses, nostalgia or paranoia.

On the molecular level, marijuana, or cannabis, is a psychoactive drug that stimulates cannabinoid receptors in the brain and the immune system.

Many of these receptors are in the part of the brain that regulates memory, concentration, pleasure, and sensory and time perception. Marijuana abuse can therefore lead to short-term memory loss and problems with learning, according to NIDA.

Studies have shown chronic marijuana use to be associated with increased anxiety and depression, though no definitive assessment has determined whether the drug causes or exacerbates the problems, according to NIDA. Some heavy users may self-medicate for existing symptoms of problems, according to NIDA.

But most people who use marijuana smoke the equivalent of a quarter of a cigarette in terms of the weight of the material, Greenland said. At that level, the quantity is too small for any harmful side effects to be detected, he added.

Despite the cultural stigma, marijuana is also used medically in small doses in lieu of traditional medicines, according to Susan Leahy, manager of The Farmacy, the only medical marijuana dispensary in the Westwood area.

The drug is not as hard on the liver and organs as other pain medications such as Vicodin and OxyContin, Leahy said.

Many who use medical marijuana report that the drug is in fact more effective than those doctors typically prescribe and cheaper to obtain, Greenland said.

Though not a cure, medical marijuana relieves the symptoms of ailments such as attention deficit disorder, multiple sclerosis, arthritis, insomnia and stress, Leahy said.

Marijuana stimulates cannabinoid receptors that control nausea, relieve pain and stimulate appetite in cancer and AIDS patients, according to Dr. Gonzalo Ruiz of The Holistic Clinic, which provides medical marijuana evaluations.

“I remember an elderly patient with inoperable lung cancer who was dying before my eyes. She didn’t want to eat or do anything,” Ruiz said. “(With cannabis) all of a sudden she perked up, started eating and had a better quality of life.”

Marijuana is a Schedule 1 substance in the United States, which means it has a high potential for abuse and no widely accepted medical use. Doctors therefore cannot prescribe medical marijuana but can only give recommendations.

Most of Ruiz’s patients have already tried many traditional treatments with little success.
“What I see is what I call a Michael Jackson effect: the ever-increasing need for stronger medication,” he said. “You’ll see a person a year later, and it’s very likely they’re on a lot of medication, and it’s much stronger. With marijuana, their dosage has not changed. And that I find very promising.”

But the jury is still out on the long-term effects of marijuana because of the difficulty in obtaining approval for such a study in the United States, Greenland said. Because the federal government has been very strict compared to many states, it’s uncertain when researchers will be able to clear the air, he added.
