[Cannabis: Similarities and differences with tobacco]

Area of Science:

• Pharmacology
• Toxicology
• Public Health

Background:

• Nicotine is the psychoactive component of tobacco, while tetrahydrocannabinol (THC) is the active compound in cannabis.
• Cannabis inhalation differs from tobacco smoking, involving larger puffs, deeper inhalation, and longer retention.
• Concomitant use of tobacco and cannabis complicates addiction evaluation.

Purpose of the Study:

• To compare the physical and psychological effects of tobacco and cannabis.
• To identify side effects specific to cannabis use.
• To examine the impact of synthetic cannabinoids.

Main Methods:

• Comparative analysis of pharmacological and physiological effects.
• Review of clinical observations and case studies.
• Examination of toxicological profiles.

Main Results:

• Both tobacco and cannabis share physical side effects on pulmonary, cardiovascular, endocrine, and stomatological systems.
• Cannabis use is associated with unique gastrointestinal issues like cannabinoid hyperemesis.
• THC can cause acute psychological effects (e.g., altered perception, cognitive impairment) and chronic issues (e.g., amotivation, psychosis exacerbation).
• Synthetic cannabinoids exhibit enhanced psychotropic and somatic effects.

Conclusions:

• Cannabis and tobacco share some health risks, but cannabis presents distinct gastrointestinal and psychological challenges.
• Understanding these differences is crucial for accurate diagnosis, treatment, and public health strategies.
• The heightened effects of synthetic cannabinoids warrant specific attention due to increased receptor affinity.
