This year, Easter grass may not only be for lining your basket. Today, Christianity's holiest day shares the calendar with\u00a04\/20,\u00a0a sort of underground holiday for pot smokers. So while some dressed in their Sunday best, attended\u00a0sunrise services and watched their children search the yard for colorful Easter eggs, others broke out their bongs, put on some reggae and\u00a0prayed at the\u00a0altar\u00a0of weed. While jokes have abounded on social media about the two "holidays" falling on the same day, the question remains: Should\u00a04\/20 really be cause for celebration?\u00a0 For once, it seems, the church and the scientific community are on the same page. The answer is no. Pastors were quick to take\u00a0advantage of the coincidence, inviting congregants\u00a0and converts alike to forgo drugs and get high on God instead.\u00a0"You can\u2019t get any higher than RISEN,\u201d states the Freedom\u00a0Church in\u00a0 Los Angeles on its website.\u00a0In Mississippi, The Church Triumphant Global will hold a "Reverse 420 \u2013 'God Keeps Me High' " concert on Sunday. According to the church website, the event "will educate and inspire our youth to stay far, far, away from marijuana." The church is facing an uphill battle.\u00a0The public's' views on\u00a0marijuana have been shifting toward legalization and a sizable percentage of Americans (38%)\u00a0in 2013\u00a0admitted to having tried the drug.\u00a0It is the most commonly used illicit drug in the country, a 2012 government survey\u00a0found. An estimated 18.9 million Americans aged 12 and older -- or 7.3\u00a0percent -- said they had used marijuana in the last month. And this year, residents of Colorado and Washington can celebrate\u00a04\/20 with legal recreational marijuana. This is not good news, according to a growing number of researchers.\u00a0Addiction specialists and neurologists say marijuana use does not come without risk, pointing to\u00a0studies that have found cannabis use can lead to serious mental and physical problems -- especially in younger users. Even Once-a-Week Weed Use Changes Brain A study published\u00a0this month in the\u00a0Journal of Neuroscience\u00a0has found that even casual once-a-week use of marijuana by\u00a0adolescents can cause critical brain\u00a0changes.\u00a0\u00a0And long-time users who try to quit report withdrawal symptoms including irritability, sleeplessness,\u00a0decreased appetite, anxiety and drug craving.\u00a0Estimates from research suggest that about 9 percent of users become\u00a0addicted to marijuana, which increases among those who start young (to about 17 percent, or 1 in 6) and among people who use marijuana daily (to 25 percent to 50 percent). \u201cThe attitude toward marijuana changed when we started to get legalization," Dr. David Sack, CEO of Promises Behavioral Health, told Fox News. "There\u2019s a perception that marijuana is safe, if\u00a0not helpful, but the evidence is to the contrary. Marijuana, especially\u00a0when used by adolescents and young adults, affects future development and thinking.\u201d Is marijuana addictive? The National Institute on Drug Abuse says it is. According to\u00a0its \u201cMarijuana Abuse\u201d research report,\u00a0\u201cLong-term marijuana use can lead to addiction; that is, people have difficulty controlling their drug use and cannot stop even though it interferes with many aspects of their lives." The Office of National Drug Control Policy\u2019s abovetheinfluence.com\u00a0website states flat out:\u00a0 \u201cMarijuana is addictive, with more teens in treatment with a primary diagnosis of marijuana dependence than for all other illicit drugs combined. Dramatic Increase in Admissions to Rehab Sack said there has been a dramatic increase in the number of people admitted to rehab for marijuana rather than other drugs, adding that "the increase in active cannabinoids that have been cultivated by growers specifically to make marijuana more powerful has also made it more addictive." The study in the Journal of Neuroscience, a collaboration between Northwestern University\u2019s medical school, Massachusetts General Hospital and Harvard Medical School, found that the parts of the brain that control motivation are compromised in marijuana smokers, a phenomenon memorialized in the song "Because I Got High" by Afroman. "I was gonna clean my room, until I got high. I was gonna get up and find the broom, but then I got high. My room is still messed up and I know why. Because I got high, because I got high, because I got\u00a0high." It is safe to say that, in the pot-smoking community, not much will be getting done today.
