Cannabis smoking and tobacco cigarettes look vaguely similar from the outside. But on the inside of your body, they’re very different from each other.

Traditional cigarettes are made from tobacco, a plant native to North and South America. After the plants have been harvested, tobacco farmers “cure” (dry) the leaves for use in an array of products, including chewing tobacco, and, as we’ll focus on here, tobacco cigarettes (and cigars).

Most species of tobacco belong to a genus called Nicotiana, which gives us the word “nicotine.” Depending on the plant species, nicotine might comprise anywhere from about 0.6% to 3% of the tobacco plant’s dry weight. Nicotine is a stimulant, which means it increases (stimulates) physiological functions. For example, nicotine can speed up your metabolism, increase your heart rate, and elevate your blood pressure. Being a stimulant doesn’t necessarily make a drug dangerous. (If it did, the caffeine in your morning coffee would likely be a scheduled substance.)

Nicotine is very dangerous because, in addition to being highly addictive – “as addictive as cocaine or heroin,” according to former U.S. Surgeon, it’s also known to have adverse effects on virtually every system of the body, including the cardiovascular system (like the heart), the excretory system (like the kidneys), and, of course, the respiratory system (like the lungs). While adverse effects are all but guaranteed with prolonged tobacco use, they are extremely rare in Cannabis users, including self-described “heavy” or “daily” users. In part, that is because Cannabis – in which the active ingredients are cannabinoids, flavonoids, and terpenes – do not contain nicotine. Of course, nicotine isn’t the only dangerous substance contained in tobacco cigarettes. Here are a few other harmful ingredients found in tobacco cigarettes but not in properly grown Cannabis products:



•Lead Cigarettes also contain tobacco-specific nitrosamines, or TSNAs.

Nitrosamines are chemical compounds that exist in dozens of foods and drinks you consume every day, including beer, bacon, and certain types of fish and cheese. While some nitrosamines are harmless, most of them are carcinogenic, which means they cause cancer over time.

As the name should make clear, tobacco-specific nitrosamines, which develop during the curing process, are unique to tobacco cigarettes. In addition to all the man-made ingredients added to tobacco cigarettes, the tobacco itself is harmful. The act of  burning tobacco – creates a nasty byproduct you’re already familiar with: black, sticky tar. Burning Cannabis can also produce tar, which is why patients are urged to avoid combustion and vaporize their Cannabis instead. Vaporization heats the Cannabis to a temperature that is hot enough to release cannabinoids like THC (Tetrahydrocannabinol), but not hot enough to result in the combustion process that creates tar. A study published in Harm Reduction Journal in 2007 found that “the respiratory effects of Cannabis can decrease with the use of a vaporizer. The data reveal that respiratory symptoms like cough, phlegm, and tightness in the chest increase with cigarette use and [C]annabis use, but are less severe among users of a vaporizer.” In short, vaporization is the safest method of using medical marijuana.

No substance is 100% harmless. Even water can be dangerous when ingested in great enough quantities. While Cannabis cannot be called absolutely safe, and indeed should be avoided by individuals who have or are predisposed toward certain types of cardiovascular problems, its use has not resulted in millions of deaths and cancer cases, in stark contrast to tobacco and nicotine.

Cannabis has never been directly responsible for a death, because the amount necessary to overdose is not physically possible to ingest. In addition to being much safer than tobacco, Cannabis also offers an array of health benefits that tobacco cigarettes do not. To provide a few examples of marijuana’s health benefits, Cannabis has been shown to alleviate pain, reduce nausea, elevate mood, and even contribute to maintaining a healthy weight. If you live in Massachusetts and have been diagnosed with a serious health condition, such as multiple sclerosis, Parkinson’s disease, hepatitis C, or Crohn’s disease, medical Cannabis may offer fast-acting and gentle relief from your symptoms, with mild and minimal side effects.


Medical marijuana is a controversial topic. In the ceaseless battle of clashing opinions among journalists, police departments, attorneys, medical doctors, social activists, and legislators, it’s all too easy to feel overwhelmed by media sensationalism and hyperbole. Unfortunately, this means the people who stand to benefit most from the use of medical marijuana — individuals who suffer from serious health conditions — are never given the chance to make informed decisions based on fact and evidence. In truth, numerous studies published in renowned, peer-reviewed medical journals such as Neurology, Rheumatology, Annals of Internal Medicine, the American Journal of Clinical Oncology, and the British Journal of Clinical Pharmacology have all documented significant health benefits associated with the use of medicinal Cannabis across a wide range of ages, races, genders, and health conditions. Do you experience any of the following medical conditions?



•Chronic Pain

•Crohn’s Disease/IBD (Inflammatory Bowel Disease)



•Hepatitis C


•Lou Gehrig’s Disease/ALS (Amyotrophic lateral sclerosis)

•Multiple Sclerosis (MS)

•Parkinson’s Disease (including Early-Onset)

•PTSD (Post-Traumatic Stress Disorder)

•Rheumatoid Arthritis

If you’re at least 18 years old and your quality of life is being negatively impacted by one of the above health issues, medical Cannabis may be able to help you simply and safely manage your symptoms. 


  1. New Kids on the Block is my favourite band of 90s. NKOTB had so many hit songs! The ones I remember are ‘Tonight’, ‘Baby, I Believe In You’ and their hit ‘Step By Step’.
