A limited number of studies have examined the effects of cannabis smoking on the respiratory system. Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis. The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease. Short-term use of cannabis is associated with bronchodilation. Other side effects of cannabis use include cannabinoid hyperemesis syndrome.
Cannabidiol, or CBD for short, is a natural phyto-cannabinoid (or plant-based chemical compound) found in cannabis plants, including hemp and marijuana. Unlike other cannabinoids — namely tetrahydrocannabinol, or THC — CBD does not produce any psychoactive effects, and will actually counteract these effects to a degree. CBD will induce feelings of sleepiness; for this reason, it can be an effective soporific for people who struggle to fall and/or remain asleep due to insomnia and other sleep disorders.
Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.
In the 1950s, the Narcotics Control Act and the Boggs Act stiffened penalties for marijuana possession, with first-time offenses requiring two to 10 year sentences and a minimum $20,000 fine, according to PBS.org. Penalties were relaxed in the 1970s, but President Ronald Reagan increased federal penalties for marijuana possession in the 1980s. On the federal level, marijuana is now regulated under the Controlled Substances Act as a schedule 1 drug, meaning the government considers it to have a high potential for abuse with no legitimate medical or therapeutic uses.

With President Trump signing off on the Agricultural Improvement Act of 2018 (aka the 2018 Farm Bill) last month, the federal government now fully recognizes hemp as a legal agricultural product. But while many reports are claiming that this means that cannabidiol (CBD) is also legal, that’s not quite correct. With a lot of misinformation flying around, and contradictions between state and federal laws, things are admittedly somewhat confusing. Let’s try to sort things out by answering some questions about hemp, CBD, and what has recently changed in federal law.
When elected to the presidency of the RACGP he said, “I will be passionate and vocal in advocating for primary healthcare and look forward to the challenge ahead”. Dr Seidel we hope that you can rise to the challenge of introducing Medicinal Cannabis to the mainstream of General Practice through education and encouragement of your peers. We strongly welcome you and thank you for your participation at this symposium.
His parents took him to more than 20 doctors around the country, and he tried more than a dozen medications. Nothing worked. Two years ago, the Leydens were at the end of their rope. They decided to see whether marijuana might help. (Medical use of the drug is legal in the District, where they live, and the Leydens found a doctor willing to work with them.) In 2014, Jackson got his first dose of cannabis.
Colorado's first and oldest medical cannabis law is a citizens’ initiative called Amendment 20 that amends the state constitution to authorize patients to possess and use medical cannabis and to be assisted by a caregiver. Colorado's second medical cannabis law, the Colorado Medical Marijuana Code (C.R.S. 12-43.3-101 et seq.), was enacted by the legislature in the summer of 2010 to establish a dual licensing mechanism that regulates medical cannabis business at both the state and local level.
Cannabis is predominantly dioecious, having imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants. "At a very early period the Chinese recognized the Cannabis plant as dioecious", and the (c. 3rd century BCE) Erya dictionary defined xi 枲 "male Cannabis" and fu 莩 (or ju 苴) "female Cannabis". Male flowers are normally borne on loose panicles, and female flowers are borne on racemes.
The endocannabinoid system is tonically active in control of pain, as demonstrated by the ability of SR141716A (rimonabant), a CB1 antagonist, to produce hyperalgesia upon administration to mice (Richardson et al 1997). As mentioned above, the ECS is active throughout the neuraxis, including integrative functions in the periacqueductal gray (Walker et al 1999a; Walker et al 1999b), and in the ventroposterolateral nucleus of the thalamus, in which cannabinoids proved to be 10-fold more potent than morphine in wide dynamic range neurons mediating pain (Martin et al 1996). The ECS also mediates central stress-induced analgesia (Hohmann et al 2005), and is active in nociceptive spinal areas (Hohmann et al 1995; Richardson et al 1998a) including mechanisms of wind-up (Strangman and Walker 1999) and N-methyl-D-aspartate (NMDA) receptors (Richardson et al 1998b). It was recently demonstrated that cannabinoid agonists suppress the maintenance of vincristine-induced allodynia through activation of CB1 and CB2 receptors in the spinal cord (Rahn et al 2007). The ECS is also active peripherally (Richardson et al 1998c) where CB1 stimulation reduces pain, inflammation and hyperalgesia. These mechanisms were also proven to include mediation of contact dermatitis via CB1 and CB2 with benefits of THC noted systemically and locally on inflammation and itch (Karsak et al 2007). Recent experiments in mice have even suggested the paramount importance of peripheral over central CB1 receptors in nociception of pain (Agarwal et al 2007)
