More studies needed on the effects of marijuana
By Dr. Anthony Policastro
Advances in medicine allow us to learn more details about medical issues. We have known for many years that using marijuana affects motivation and short term memory. We did not know how that happened or if it was temporary. We also did not know how long the effects lasted. With the current push for legalizing marijuana, it is important to try and find that out. Earlier this year researchers from Boston published an article in the Journal of Neuroscience. These researchers conducted brain MRI scans on a group of individuals. Most were college students in the Boston area. They broke them into four groups. One group did not use marijuana at all. One group was classified as light users (once a week or less). Another group was classified as moderate users (four to seven days per week). One group consisted of daily users. The studies showed that the MRI scans had two areas that were different in smokers compared to non-smokers. One area controls motivation. The other area is involved in memory. The unexpected finding was that the changes affected all the smokers. It did not matter if they were light or daily smokers. The changes still existed. We have long known that frequent use of marijuana causes amotivational syndrome which results in an unwillingness to do very much that is productive. This study supports the fact that there are actual brain changes to go along with that. A related issue has to do with the actual concentration of tetrahydrocannibol (THC) - the active ingredient. The amount of active ingredient used to be pretty low. In 1995 it was only about 3.75% of the total used. Over the years, more concentrated blends have been grown. Most strains now contain about 13% THC. One firm in Colorado is advertising "Green Crack" with a concentration of 21%. With the stronger concentrations come other dangers. ER visits for marijuana reactions doubled from 2004 to 2011 when there were 129,000 such visits. A June article in the New England Journal of medicine found that high dose marijuana was associated with higher risk of paranoia and psychosis. Another effect of the higher dose marijuana is addiction. The rate of addiction is higher in younger users standing at one out of six users. It is only one out of 11 for adult users. At this point the studies are still early. The Boston study was very small. The results will need to be confirmed by additional studies. The question becomes how many states will legalize marijuana use before we confirm how significant the effects are on the human brain?
Nanticoke welcomes coordinator For patients with serious illnesses and their families, finding the support services they need and coordinating with a team of doctors, nurses, case managers and specialists can be overwhelming. That's why Nanticoke now has a palliative care coordinator available to help. Patients referred to a palliative care program can include those with cancer, cardiac disease like congestive heart failure, chronic obstructive pulmonary disease, kidney failure, ALS and many other illnesses. Palliative care coordination can also help patients undergoing life prolonging treatments. The palliative care coordinator is a resource that can help patients with relief from symptoms like pain, shortness of breath, fatigue, constipation, nausea, loss of appetite, difficulty sleeping, stress and depression. The palliative care team can help patients and families with complex decisions about care and treatment. For more information about Nanticoke's program, call Kathy James, NP and palliative care coordinator at 629-6611, ext. 3115.

The site is available at www.deradiationprotection.org. "The webpage provides a guide to user-friendly information for patients and parents to learn more about many medical procedures involving radiation, as well as robust learning resources for science teachers and students," said Dr. Frances Esposito, DARP chairman, and chief of radiology at Beebe Healthcare.
