Cannabis Nurse Truths
Cannabis Nurse Truths is the voice of reason in a bureaucracy of nonsense. Dr. Denise Foster, PhD, MSN, RN, CNE is a nationally-recognized expert on the medicinal use of cannabis. She teaches doctors, nurses and other educators in its use in modern medicine. We talk about all things cannabis and highlight the research that continues to indicate that cannabis is medicine.

Previous research has indicated that driving impaired while under the influence of cannabis can increase safety concerns for both driver and passengers, and that cannabis users are more likely to drive while impaired because of the perception that drugged driving is not as risky as drunk driving.
However, prior driving research studies focused mainly on healthy individuals using intoxicating levels of THC, which do not provide real-world evidence of how new paradigms, such as medical cannabis, influence driving while high. In this episode of Cannabis Nurse Truths, we examine the safety concerns and current attitudes related to driving while high, and we emphasize an immediate need for more reliable drug testing methods and public education campaigns.

Cannabis users are both considered criminals and protected under federal laws. What a mess. One of the most significant issues surrounding cannabis use, especially in states where medical marijuana is legal, is the ability to use state-sanctioned medical marijuana, which is typically protected under disability laws, but yet can also be punitive as employers are allowed to terminate employees for cannabis use. Another pressing concern is how workers’ compensation activities will be affected by an employee’s medical marijuana use.
In this episode of Cannabis Nurse Truths, we continue to review how privacy laws, medical freedom, and workers’ compensation issues all have a significant impact on employers’ workplace policies, and we offer recommendations that employers should begin to consider as cannabis legalization is likely implemented in the near future.

Cannabis legalization will have a profound impact across all levels of society. One of the most significant effects of cannabis legalization relates to employment. Employers have a financial interest in ensuring that employees are not intoxicated on the job and will not create a safety hazard related to impairment risks. On the other hand employers must also adhere to strict privacy and ADA guidelines which may conflict with federal requirements associated with a drug free workplace.
In this episode of Cannabis Nurse Truths, we review the concerns related to cannabis legalization in the workplace in which employers must be aware of the rapidly changing laws and regulations in order to help them develop legally defensive workplace policies that also legally balance the health needs of their employees who use cannabis.

Our past several episodes have focused on how cannabis use is harmful across all stages of pregnancy, from the prenatal to the lactation period. However, there is another person in this equation that results in a pregnancy, and until just recently, men have been largely left out of the research regarding the effects of cannabis use in relation to reproduction. That is changing as increased legalization and access to cannabis has researchers examining the effects of its exposure on male reproduction.
In this episode of CNT, we highlight the adverse effects of cannabis exposure in men that may create long-term genetic changes in their offspring. From the accumulating evidence, we can state with certainty that men who are interested in contributing to a pregnancy should refrain from cannabis use, as it affects not only sperm cells but can also create harmful DNA alterations that are hereditary. In other words, men should also just say no if they plan on contributing to a pregnancy.

We continue to examine cannabis use during pregnancy, and in the last few episodes of Cannabis Nurse Truths, we highlighted the adverse physical and psychodevelopmental concerns that are associated with cannabis during pregnancy. None of the studies indicated that cannabis use during pregnancy was a good idea.
In this episode of CNT, we consider the effects of cannabis use AFTER pregnancy, the postpartum period, in which many new mothers choose to breastfeed their newborn. Research indicates that cannabinoids are transferred through breast milk and remain in the breast milk for up to 6 weeks. Since we already know that cannabinoids can affect fetal development during pregnancy, it is concerning that women who use cannabis during breastfeeding are also affecting the developing neuromodulatory systems of their newborn. In other words, it is also a good idea to just say no during the postpartum period if you are a breastfeeding mother.

In our last episode of Cannabis Nurse Truths, we highlighted the adverse physical concerns associated with using cannabis during pregnancy that can result in outcomes like low birth weight and long-term metabolic disorders. In this episode, we review the developmental and psychological concerns associated with cannabis during pregnancy.
Research suggests that prenatal cannabis exposure in any trimester can cause specific deficits as well as behavioral excesses in the offspring, even a decade after exposure. In other words, it's never a good time to use cannabis during pregnancy

Prenatal cannabis exposure is associated with a higher risk of many different forms of birth defects and long-term neurodevelopmental effects. Cannabis during pregnancy not only exposes the developing fetus to harmful outcomes, but also can create adverse effects for offspring later in life.
In this episode of CNT, we review these known adverse birth outcomes, which underscores the significance of implementing preventative strategies for guiding cannabis use during pregnancy. The bottom line: Just Say No.

Cannabidiol, or CBD, was discovered in 1940 by Dr. Roger Adams in a sample of hemp he was testing for intoxicating compounds. Prior to the discovery of THC in 1964, scientists were busy looking for the magic ingredient that caused all of the impairing effects of cannabis and happened upon CBD during their search. Fast forward to modern day research, where we now understand how CBD works in the body to create many beneficial physiological and psychological effects.
On this episode of CNT, we highlight the wonders of CBD, the miracle drug that seems to be able to affect numerous chronic conditions, including hypertension, cancer, neurodegenerative disease, and even COVID-19 infection. It can also prevent numerous conditions, such as autoimmune and psychological disorders. So, why isn't CBD part of your daily wellness regimen?

Cannabis is the most over regulated, yet under regulated prohibited drug on the market - and the most studied! Through eight decades of research, we know of all of the potential harms and risks associated with both use of the plant and access to the plant. Lab testing of all cannabis products is what helps keeps our consumers safe. But what if that's not the case?
On this episode CNT, we review cannabis testing industry considerations and highlight some of the issues we are already facing as we try to provide safe, lab-tested products to either medical or adult use consumers.

Medical or adult use? Which should you use? What are the differences? Are there differences? Currently in the United States, cannabis users have two legal options in states that have legalized either medical or adult-use cannabis. Although many of the differences between them are related to access, there are many other issues at hand when consumers make the decision to purchase at either a legal adult-use or medical dispensary.
In this episode of CNT, we highlight the differences between medical and adult-use cannabis, but keep in mind... it's all the same weed.
