Research from Washington State University suggests cannabis could be used to relieve headaches, university researchers said in the Journal of Pain.According to the research, inhaled cannabis reduces self-reported headache severity by 47.3% and migraine severity by 49.6%. According to Washington State, the study was the first to use big data from headache and migraine patients using cannabis in real time. “We were motivated to do this study because a substantial number of people say they use cannabis for headache and migraine, but surprisingly few studies had addressed the topic,” said Carrie Cuttler, a Washington State University assistant professor of psychology, the lead author on the paper.Cuttler did caution that there could be a placebo effect, and that further research is needed.“I suspect there are some slight overestimates of effectiveness,” said Cuttler. “My hope is that this research will motivate researchers to take on the difficult work of conducting placebo-controlled trials. In the meantime, this at least gives medical cannabis patients and their doctors a little more information about what they might expect from using cannabis to manage these conditions.”The study also found no significant difference between the effectiveness of THC and CBD, two active ingredients in cannabis.One prior study indicated that cannabis was more effective than ibuprofen in reducing headaches, but that study used nabilone, a synthetic cannabinoid drug. 1480

Super Blood Wolf Moon Eclipse. No, it's not a death metal band — it's a rare lunar phenomenon that will occur on Jan. 20.The super blood wolf moon eclipse is actually just the concurrence of three separate phenomena — a lunar eclipse, a super moon and a wolf moon. A lunar eclipse occurs when the Earth is positioned between the sun and the moon, casting the moon completely in the Earth's shadow and giving it an organish, "bloody" look. Full lunar eclipses occur between two and four times a year.A supermoon occurs when the moon is within 90 percent of its closest possible distance to the Earth. According to 625

Summer is in full swing, and with the warmer months comes the mosquitoes. Not only are the small insects pesky, they are considered the deadliest animal in the world, believe it or not. More than 700 million people around the globe get sick from mosquito bites, and more than 700,000 people die from those bites each year."We always see West Nile Virus peaks right after the Fourth of July weekend, because people have been outside and not protecting themselves," says Kylee Grenis, an expert on mosquitoes. Grenis helped us conduct an experiment to find out which bug repellent works the best.We purchased three mosquito traps. We sprayed one trap with DEET. The other with a top rated non-DEET spray called Skin So Soft by Avon. The third trap was a controlled trap with no spray.The traps were hung next to dry ice in a mosquito-infested park."We are going to hang some dry ice near those traps to simulate a human standing and breathing and hopefully that will help attract more mosquitoes to our traps," explains Grenis on the use of dry ice. After an hour, the trap sprayed with DEET had one mosquito. In the Avon-sprayed trap, there were no mosquitos. In the control trap, there were six mosquitos. The sprays kept the mosquitos away.As far as sprays go, Grenis says she still prefers DEET. "It is great at making you invisible to mosquitoes,” she says. “That blocks the receptors so that they can't detect your carbon dioxide signature." But, many consumers fear products with DEET are not safe. "I think a lot of the time people get it confused with DDT,” she explains of Dichlorodiphenyltrichloroethane (DDT), a chemical compound banned in many countries due to the danger it poses to wildlife and the environment.DEET is safe to use and just like the Avon spray, and both sprays are effective in keeping mosquitos away during the summer time months. 1872
