Smoking & Vaping Effects: Uncovering the Truth with Dr. Peter Attia

Ari Horesh

In an enlightening YouTube video, Dr. Peter Attia and Dr. Andrew Huberman delve into the health impacts of smoking and vaping, particularly focusing on marijuana and nicotine. Their discussion sheds light on common misconceptions and provides critical insights into the risks associated with these practices.

The Misconception About Cannabis Smoking

"I can certainly tell you that there's no reason to believe that smoking cannabis is somehow better than smoking cigarettes..."

Dr. Attia clarifies a widespread belief that smoking cannabis is less harmful than cigarettes. However, the comparison isn't straightforward. He introduces the concept of a 'pack-year' smoker to quantify the risk levels associated with different smoking habits, highlighting that the quantity and duration significantly impact health risks.

Cannabis vs. Tobacco: A Closer Look

Despite the lower frequency of cannabis smoking compared to tobacco, it doesn't imply safety. Dr. Attia stresses that even a lower dose of cannabis smoke carries health risks, although likely less severe than heavy tobacco use.

Vaping: A Lesser Evil?

Regarding vaping, Dr. Attia expresses concern. He acknowledges that while vaping might be less harmful than traditional smoking, it is far from a safe alternative.

"Vaping isn't good for you, but it's not as bad as smoking."

He suggests that vaping could be a transitional step for those struggling to quit smoking, but emphasizes it's not an ideal solution.

The Chemical Risks of Vaping

Dr. Huberman raises alarms about the chemical constituents in vape products. The presence of carcinogens and their ability to cross the blood-brain barrier is particularly troubling, posing serious long-term health risks.

Cannabis: Medical Benefits and Risks

The conversation shifts towards the medical applications of cannabis. Dr. Huberman notes that while cannabis can be beneficial, especially in forms like CBD for epilepsy, high THC levels, especially in young males, can lead to severe mental health issues.

The Unseen Dangers of Inhalation

A striking point made by Dr. Attia is the vast surface area of the lungs and their efficiency in gas exchange. This trait makes the lungs highly vulnerable to harmful substances present in smoke or vape.

"Anytime you inhale something, your body is so adept at absorbing it..."

He also touches upon air pollution's impact, arguing that the health risks of particulate matter are a compelling argument for cleaner energy.


In summary, Dr. Attia and Dr. Huberman's discussion provides an in-depth analysis of the risks associated with smoking and vaping. They highlight the importance of understanding the health implications and urge caution, advocating for safer alternatives.

Key Takeaways

  • Cannabis Smoking vs. Cigarettes: Both carry risks, but the frequency and amount significantly impact health outcomes.
  • Vaping: Not a safe alternative to smoking, but possibly a lesser evil.
  • Medical Cannabis: Beneficial in some forms but not without risks.
  • Inhalation Risks: Awareness of what we inhale is crucial, given the lung's efficiency in absorbing substances.

In conclusion, the video serves as a critical reminder of the importance of making informed choices about our health, particularly regarding smoking and vaping habits.
