Trends and Factors Related to Blunt Use in Middle and High School Trends and Factors Related to Blunt Use in Middle and High School Students, 2010–2020 Mohammad Ebrahimi Kalan, PhD,a Rime Jebai, MPH,a Zoran Bursac, PhD,b Lucy Popova, PhD,c Prem Gautam, MPH,a Wei Li, MPH,a Mohammed M. Alqahtani, MS,d Tanjila Taskin, MPH,a Leah L. Atwell, MPH,e Jennifer Richards, MPH,e Kenneth D. Ward, PhD,f Raed Behaleh, PhD,g Ziyad Ben Taleb, MD, MPH, PhDh BACKGROUND AND OBJECTIVES: Blunt use is a popular mode of marijuana consumption among abstract adolescents in the United States, but little is known about how its prevalence has changed over time or factors associated with its use. With this study, we assessed trends and correlates of past (ever used but not in the past 30 days) and current (used in past 30 days) blunt use among adolescents in Florida. METHODS: We analyzed data from 2010–2020 cross-sectional, statewide representative Florida Youth Tobacco Surveys that comprised 461 706 middle and high schoolers using Joinpoint to calculateannualpercentagechange(APC)intheweightedprevalenceofpastandcurrentblunt use. A weighted multivariable regression model was developed by using 2019–2020 Florida Youth Tobacco Survey data to examine the factors associated with past and current blunt use. RESULTS: Whereas the prevalence of past (APC 5 À5.32%)andcurrent(APC5 À5.28%)bluntuse significantly decreased from 2010 to 2015, an increasing trend in current use prevalence (APC 5 14.91%) was observed from 2015 to 2018 and has been approximately constant ever since. Similar increasing trends were observed in current blunt use among female students (APC 5 14.92%), middle schoolers (19.57%), and non-Hispanic (NH) white students (APC 5 11.12%) from 2016 to 2020. Several factors were consistently associated with greater odds of both past and current blunt use for both middle and high schoolers, including older age, being NH Black (versus NH white), past and current use of cigarettes, electronic cigarettes, hookah, cigars, and ever vaping marijuana. CONCLUSIONS: Although blunt use among Florida youth decreased from 2010 to 2015, substantial increases were observed since 2015, suggesting that existing tobacco control programs should incorporate marijuana (and blunt) modules into existing tobacco and nicotine prevention programs.

  • Cannabis As Plant and Product
    1 Cannabis as Plant and Product Marijuana is subject to numerous misconceptions and con- fusion. There is disagreement on some basic issues, such as how the cannabis plant grows, how it interacts with the body, where it comes from, and how long it has been in use. Before jumping into a discussion of marijuana policy, it is important to dispel these misconceptions regarding the plant and its products. Some popular misconceptions include that marijuana is easy to grow, that it can grow under almost any conditions, and that it’s pretty much the same everywhere. You grow it, pluck its flowers, dry them, wrap them in rolling paper, and smoke it, and there you have it, your weed, or pot, or Mary Jane. In reality the cannabis plant is biologically complex, and the production of marijuana is not as simple as many people believe. 9 Hudak_Marijuana 2nd Ed_a,b_i-xiv_1-252.indd 9 5/11/20 9:51 AM 10 MARIJUANA In addition, marijuana has changed over time with in- novations in growing, harvesting, and generating products. Marijuana is no longer something you pack into a bowl, roll in a joint, smoke in a bong, or lace into some brownies. It’s now a diverse consumer product available in many forms. The Cannabis Plant Members of the Cannabis genus are leafy, flowering plants that are native to Central Asia but have been transported and grown throughout the world. The plant has been around for millions of years in some form and has been used by humans for at least 5,000 years.1 It tends to be robust and grows effectively in both natural and controlled agricultural settings.

  • Blunts and Blowt Jes: Cannabis Use Practices in Two Cultural Settings
    Free Inquiry In Creative Sociology Volume 31 No. 1 May 2003 3 BLUNTS AND BLOWTJES: CANNABIS USE PRACTICES IN TWO CULTURAL SETTINGS AND THEIR IMPLICATIONS FOR SECONDARY PREVENTION Stephen J. Sifaneck, Institute for Special Populations Research, National Development & Research Institutes, Inc. Charles D. Kaplan, Limburg University, Maastricht, The Netherlands. Eloise Dunlap, Institute for Special Populations Research, NDRI. and Bruce D. Johnson, Institute for Special Populations Research, NDRI. ABSTRACT Thi s paper explores two modes of cannabis preparati on and smoking whic h have manifested within the dru g subcultures of th e United States and the Netherlan ds. Smoking "blunts," or hollowed out cigar wrappers fill ed wi th marijuana, is a phenomenon whi ch fi rst emerged in New York Ci ty in the mid 1980s, and has since spread throughout th e United States. A "bl owtj e," (pronounced "blowt-cha") a modern Dutch style j oint whi ch is mixed with tobacco and in cludes a card-board fi lte r and a longer rolling paper, has become th e standard mode of cannabis smoking in the Netherl ands as well as much of Europe. Both are consid ered newer than the more traditi onal practi ces of preparin g and smoking cannabis, including the traditional fi lter-less style joint, the pot pipe, an d the bong or water pipe. These newer styles of preparati on and smoking have implications for secondary preventi on efforts wi th ac tive youn g cannabis users. On a social and ritualistic level th ese practices serve as a means of self-regulating cannabi s use.

  • The Blunt Facts – Clearing the Haze of Marijuana for Public Schools
    THE BLUNT FACTS – CLEARING THE HAZE OF MARIJUANA FOR PUBLIC SCHOOLS Summary of CA Proposition 64: Adult Use of Marijuana Act In California, it is now legal for individuals over the age of 21 to possess, transport, obtain or give away to other adults 21 or older no more than one ounce of marijuana or eight grams of concentrated cannabis. Individuals over the age of 21 may also cultivate up to six plants per residence and possess the marijuana produced by these plants. Local governments may for- bid cultivation outdoors, but must allow it inside a private residence or accessory structure that is “fully enclosed and secure.” In many respects, the impact of Proposition 64 on school districts mirrors the rules, policies and procedures with respect to alcohol possession and use. It is also important to note that medical marijuana patients keep their existing rights under Proposition 215 to possess and cultivate as much as they need for personal medical use so long as they have a doctor’s recommendation, regardless of the Proposition 64 limits for adult users. Be aware, though, that local governments may still restrict cultivation via nuisance ordinances (except for the six indoor plant minimum allowed for personal use). Testing abilities are still uncertain and fluid, which may create difficulties in certain situations. Governance and Policies Q. How should existing policies that address alcohol be modified to include recreational use of marijuana? A. Any policies that address alcohol or tobacco on or around campus, and utilization of same (i.e., BP 3513(a), 4020, etc.) should be revised to also include marijuana.

  • Youth Marijuana Use
    WHERE WE STAND: YOUTH MARIJUANA USE The increasing movement by states to legalize the recreational use of marijuana for adults highlights the importance of setting standards for the regulation of youth marijuana use. It is Truth Initiative’s position that recreational marijuana use is not appropriate for individuals under the age of 21.* Truth Initiative’s position reflects concerns raised by strong patterns of concurrent use of marijuana and tobacco1-3 – and our view that tobacco products should not be sold to persons under the age of 21. In addition, youth are increasingly using tobacco products as vehicles for marijuana use through, most commonly, “blunting”. A “blunt” is a cigar from which most or all of the tobacco is removed and replaced with marijuana.1-3 Others are combining marijuana with tobacco in cigarettes. Across all age groups, research shows that concurrent use of marijuana and tobacco places individuals at greater risk for respiratory,4-6 psychological, and substance dependence problems.7-11 Our position also reflects concerns that marijuana use is not appropriate for individuals under the age of 21, given the potential impact of marijuana (or the recreational use of any other drug, including alcohol) on adolescent brain development.12-14 Moreover, regular or daily marijuana use in young people has been correlated with negative health and social outcomes, including mental health problems and poor school performance.13,15-17 RECOMMENDATIONS Truth Initiative supports the following policies and practices to protect youth, based in large part on experience from the area of tobacco control: Any marijuana legalization policy should strictly control youth access.

  • The Blunt Truth Useful Tips About Safer Ways to Use Cannabis
    the Blunt Truth Useful tips about safer ways to use cannabis This resource has been developed for youth by youth. We did the boring research so you don't have to! (You're welcome.) You have the choice whether you want to use cannabis* (weed, pot), but you should know that there are different ways of using and some are safer than others. This resource gets down to the blunt truth about cannabis, and lets you know what science recommends to help reduce some of the risks to your health and well-being if you do choose to use cannabis. * See back for definitions Why DOES THIS MATTER? No matter how you use cannabis, there are some short- and long-term health risks. The only way to completely avoid all of the risks is to not use cannabis. But we know that’s not realistic for everyone! So, if you still want to use, or just want to know more, keep reading to learn about safer ways of using cannabis. What TYPES OF CANNABIS PRODUCTS ARE LESS RISKY? Products that have higher THC (tetrahydrocannabinol) content, the main psychoactive* compound in canna- bis, can be more harmful. These products can lead to short- and long-term problems, such as mental health concerns, dependence or injuries. CBD (cannabidiol), another compound in cannabis, can reduce some negative effects like memory impairment, paranoia and high heart rate. Fewer people experience psychotic symptoms* or other mental health problems when using cannabis that has a higher CBD content. Try to choose products with low THC content, or higher CBD compared to THC content.
